=== PART 1 ===
CASEY RIVERS: For two episodes, we've been looking up, scanning the skies for anomalies. But here's the thing... what if the biggest unknown isn't out there, but down here? Imagine this: a world of eternal night, crushing pressure, and secrets older than humanity itself. We're so focused on finding extraterrestrial life, we forget that our own planet holds a realm more alien than Mars. I'm talking about the deep ocean, the abyss. What if something ancient, something intelligent, has been watching us from the crushing dark this whole time, calling Earth home long before our ancestors ever looked to the stars? It’s an idea that’s both terrifying and, you know, completely awe-inspiring.
JORDAN HAYES: It is an alluring thought. But let's examine the facts for a moment, because they actually support why such a thing *could* remain hidden. Objectively, the deep sea is the most hostile environment on Earth for us. The pressure is immense, thousands of pounds per square inch. It’s near freezing, and there is a total absence of light. Our best submersibles are like fragile tin cans down there. Exploring the abyss isn't like sending a rover to Mars; it's vastly more difficult and expensive. That’s why the majority of our own planet remains, quite literally, unmapped and unseen. It is the perfect place to hide.
CASEY RIVERS: Exactly! And that scientific veil you mentioned, Jordan, is where the mystery really begins to breathe. Think about it. For thousands of years, cultures from every coastline on Earth have told stories of the deep. The Leviathan, the Kraken, lost cities like Atlantis submerged by the waves. We dismiss them as myths, as sailor's yarns. But what if they're not just fantasy? What if they are a kind of cultural memory, a fragmented testimony from a time when we were even more vulnerable to the ocean's power? What if those ancient sailors weren't just seeing whales or giant squid, but were brushing up against something else entirely, something truly anomalous?
CASEY RIVERS: So that’s the question we’re diving into today. Are we alone on this planet? Not in the sense of aliens from above, but of a native intelligence from below. An intelligence that might be biological, technological, or something we can’t even begin to classify. The ocean has been keeping its secrets for a very long time, but now, the evidence shows we're starting to get glimpses. Now here's where it gets interesting. We’re going to move past the folklore and look at documented cases, declassified naval reports, and unexplained sonar phenomena that suggest we are not the only ones using the world’s oceans.
CASEY RIVERS: I want everyone listening to try and picture something. Forget the maps you see in school, the ones that are mostly land with blue filling in the gaps. The reality is that our world is a water world. Over 70 percent of the surface is ocean, but that's just the surface. The deep ocean, the part below a thousand meters, makes up more than 95 percent of the entire planet's biosphere. Ninety-five percent. It is the largest single habitat for life on Earth, and we know almost nothing about it.
JORDAN HAYES: The statistics are staggering. Based on what we know from agencies like NOAA, it's often cited that more than eighty percent of our ocean is unmapped, unobserved, and unexplored. We have more detailed maps of the surface of Mars and our own Moon than we do of the seafloor on our own planet.
CASEY RIVERS: Right! And when we say "explored," that term is generous. Exploration often just means a single sonar pass from a ship miles above. The amount of the deep seafloor that has been visually surveyed by a submersible or a camera? It’s estimated to be less than 0.001 percent. Let that sink in. All the deep-sea footage you’ve ever seen, all the documentaries, all the scientific expeditions combined, have seen an area roughly the size of Rhode Island. The rest, an area larger than all the continents combined, remains in total darkness. It is Earth’s ultimate hiding place.
JORDAN HAYES: And the conditions create a perfect barrier. When Casey says "crushing pressure," we’re talking about forces exceeding 16,000 PSI in the deepest trenches. That’s the equivalent of one person trying to support the weight of fifty jumbo jets. Any organism or technology there would need to be structured in a way that is almost incomprehensible to us.
CASEY RIVERS: I mean, it’s a world built on completely different rules. It’s the sheer, mind-bending scale of the unknown that gets me. It is not a pond; it is a world within our world, silent, dark, and unimaginably vast. And in all that space, all that darkness, to assume we’re the only complex, intelligent thing on this planet… it starts to feel less like a scientific certainty and more like, you know, a failure of imagination.
JORDAN HAYES: Okay, so a failure of imagination. I can see that. But for centuries, it was also considered a scientific reality. There was a prevailing theory that the deep ocean was simply a sterile desert, right?
CASEY RIVERS: Exactly. It was called the "Abyssus theory," and for a long time, it was scientific dogma. Promoted by a naturalist named Edward Forbes in the 1840s, it basically stated that life couldn't exist below about 300 fathoms, or 550 meters. The idea was that the combination of no light, freezing temperatures, and immense pressure created a zone of death, an "azoic zone." Think about it, it makes a kind of intuitive sense.
JORDAN HAYES: Based on what we know, it's a logical assumption from the surface. So, what was the first crack in that theory? What does the evidence show that started to change minds?
CASEY RIVERS: The very first hints came much earlier, actually. Back in 1818, Sir John Ross was on an expedition to find the Northwest Passage. He was dredging the seafloor in Baffin Bay, and from a depth of over 1,800 meters, he pulled up a basket star—a complex, living organism—clinging to his sounding line. It was an anomaly, something that shouldn't have been there according to the prevailing wisdom. But it was largely ignored at the time.
JORDAN HAYES: So, an inconvenient piece of data that didn't fit the model. That happens. What made it impossible to ignore?
CASEY RIVERS: The HMS Challenger. This was the game-changer. From 1872 to 1876, this single British naval vessel undertook a monumental, four-year voyage with the sole purpose of scientific discovery. It circumnavigated the globe, taking soundings, collecting samples, and dredging the ocean floor at depths people had previously only guessed at. They didn't just find a few oddities. They discovered over 4,700 new species of marine life. They pulled creatures from the Mariana Trench itself. The Abyssus theory wasn't just challenged; it was obliterated. It proved, unequivocally, that the abyss was not a desert. It was a thriving, populated world.
CASEY RIVERS: And the kind of world they found… I mean, it’s something straight out of science fiction. The rules of life we take for granted on the surface just don't apply. Take hydrothermal vents. These are volcanic fissures on the ocean floor, spewing superheated, mineral-rich water into the crushing cold and dark. You’d think nothing could live there. But instead, you find these teeming oases, entire ecosystems that are completely independent of the sun.
JORDAN HAYES: Right, they rely on chemosynthesis, not photosynthesis. Bacteria convert the toxic chemicals, like hydrogen sulfide, into energy, and then entire food webs—tube worms, giant clams, blind shrimp—are built on those bacteria. Objectively, it is one of the most incredible discoveries in modern biology.
CASEY RIVERS: It is! It's life built on a completely different chemical foundation. And then there’s the light. Or the lack of it. Imagine this: you're floating in absolute, total blackness, a darkness more complete than anything on land. But it’s not empty. It's filled with signals. It’s estimated that over 75 percent of all animals living below the sunlit zone produce their own light. Bioluminescence. They use it to hunt, to attract mates, to communicate, to camouflage themselves with counter-illumination. It's a silent, secret language of light. You have anglerfish with their lures, vampire squid that create dazzling, disorienting patterns, and then you have creatures like comb jellies that pulse with these shimmering, rainbow-like cascades of light. It's this constant, ghostly ballet happening miles beneath our feet. These aren't just adaptations; they are reinventions of what it means to be alive, solutions to problems we can barely comprehend, like how to keep your cellular structure from collapsing under pressure that could pulverize steel. It’s an alien biosphere on our own planet.
JORDAN HAYES: It’s fascinating, Casey, truly. But let's examine the facts behind why it remains so mysterious. It's not just a lack of curiosity. There are immense, practical barriers here. The same conditions that make these life forms so unique also make them almost impossible for us to study directly.
CASEY RIVERS: Oh, absolutely. The cost is astronomical. You can't just go for a swim. The pressure, as we said, is insane. The temperatures are just above freezing. And the darkness is absolute. Building a submersible that can withstand those conditions, keep a human alive, and actually perform delicate scientific work is one of the most complex engineering challenges on Earth. A single deep-sea research vessel can cost upwards of fifty to eighty thousand dollars per day to operate. That's just to have it out on the water.
JORDAN HAYES: And that cost creates a huge bottleneck in what we can explore and where. You can't just point to a random spot on the map and decide to go. The logistics are a nightmare.
CASEY RIVERS: Exactly right. And it's created a massive geographic bias in our understanding. The evidence shows this clearly. A 2022 study in the journal Marine Policy revealed that over 65 percent of all documented visual observations of deep-sea life are concentrated in the waters near just three countries: the United States, Japan, and Mexico. Why? Because that's where the major research institutions with the funding and the technology are based. Vast swathes of the South Atlantic, the Indian Ocean, the Southern Ocean… they are effectively blank spots on the map. We have better maps of Mars and the Moon than we do of our own planet's seafloor. It’s not just unexplored; for huge areas, it’s completely unobserved.
CASEY RIVERS: But here's the thing that gets me so excited. Despite all those incredible costs and challenges, we're entering a new golden age of discovery. The technology is finally starting to catch up to our ambition. We're seeing a surge in the use of autonomous underwater vehicles, or AUVs. These are robotic submarines that can go deeper, stay down longer, and cover more ground than any human-occupied vessel, and at a fraction of the cost.
JORDAN HAYES: The data they can collect is on a completely different scale. They're mapping the seafloor in high resolution, collecting environmental DNA, or eDNA, which allows scientists to detect species just from traces of genetic material left behind in the water.
CASEY RIVERS: Exactly! And it's leading to this explosion of discovery. There are massive global initiatives underway right now, like the Ocean Census project. Their stated goal is to discover 100,000 new marine species in the first decade alone. And they are on track. Every time one of these expeditions goes out, they come back with hundreds, sometimes thousands, of potentially new species. Just recently, an expedition off the coast of Chile discovered over 100 new species living on isolated seamounts, including bizarre "spaghetti worms" and corals they'd never seen before. This is the dramatic-reveal for me: the mystery isn't static. It's not just about what we don't know; it's about the staggering rate at which we are realizing how much we don't know. We're not just filling in a map; we're discovering that the map is exponentially larger and more complex than we ever imagined. The deep ocean isn't a relic of the past; it is a dynamic, active frontier, and we are just now, in this very moment, beginning to pull back the curtain. It's genuinely mind-blowing.
CASEY RIVERS: So we're left with this incredible picture. A world within our world, larger than all the continents combined, operating under a different set of rules. A place where life thrives without sunlight, speaks in a language of light, and withstands forces that would crush our best technology. We’ve established that it’s a realm of near-total darkness, populated by beings that seem more alien than terrestrial. And despite the immense cost, we’re now discovering new ecosystems and thousands of new species at a rate that is almost difficult to comprehend. We are confirming, year after year, that the single largest biosphere on our planet is the one we know the least about. It forces you to recalibrate your entire sense of this world. Which brings me to the big question, the one that sits at the very heart of this episode. What if... what if the new species and bizarre ecosystems are just the beginning?
JORDAN HAYES: What do you mean, "the beginning"? That seems like a pretty significant area of study on its own.
CASEY RIVERS: It is. But all of that, as strange as it is, still fits within our understanding of biology and geology, more or less. We can categorize a new fish, we can study chemosynthesis. It's amazing, but it's science we can eventually wrap our heads around. But in a place so vast, so isolated, and so fundamentally alien to our own experience, is it not possible that it could conceal phenomena that lie outside those comfortable boundaries? If the ocean can hide entire ecosystems for millennia, what else might be hidden in its unfathomable depths? Because some of the accounts we’re about to explore, the documented sonic anomalies and the unexplained encounters from naval personnel, suggest that the ocean's greatest mysteries might not be biological at all. Now here's where it gets interesting.
=== PART 2 ===
CASEY RIVERS: So, we’re talking about Unidentified Submerged Objects, or USOs. And for me, the classic, foundational case has to be the Shag Harbor incident. We're going back to October 4th, 1967, in a tiny, quiet fishing village in Nova Scotia. It’s a place where the rhythm of life is tied to the ocean. You know, the air is cold and salty, the stars are brilliant over the dark water. And on this particular night, at least eleven people, completely independent of each other, reported seeing the exact same, bizarre thing. They saw a large object, maybe sixty feet across, with a series of four bright, white lights flashing in sequence. It moved silently across the sky, descended at a 45-degree angle, and then just… hit the water. But witnesses said it wasn't a violent crash like you'd expect from a plane. It was more controlled. There was a bright flash, a whooshing sound, and then this strange, glowing yellow foam started spreading out from the impact point. This wasn't one person seeing a light in the sky; this was a documented event witnessed by dozens of people on the ground, all describing this impossible object entering their waters.
CASEY RIVERS: But here's the thing, Jordan, it wasn't just a splash and it was gone. Multiple witnesses, including a local fisherman named Laurie Wickens and his friends, watched this thing. They saw it from the shore. The lights were still visible, bobbing on the surface for several minutes, moving with the tide for nearly a mile. It was as if it was perfectly intact, just floating there, before it tilted and slowly, deliberately, submerged beneath the waves and vanished completely. The Royal Canadian Mounted Police arrived on the scene, and one of the first officers, Corporal Victor Werbicki, also saw the light sink. And that foam? It wasn't sea foam. The Coast Guard cutter that arrived described a patch of bubbling, yellowish material, eighty feet wide and half a mile long. It was thick, almost like a sulphurous shaving cream, and it glittered. They tried to scoop some up in a bucket, but it just dissipated into nothing. The Royal Canadian Navy was called in, they brought divers, they did a multi-day underwater search of the seabed. And they found nothing. No wreckage, no debris, no bodies. Just that lingering, inexplicable foam. What do you make of a physical trace like that, which can't be collected and has no identifiable source?
JORDAN HAYES: Let's examine the facts, Casey. The testimony is compelling, no question. Multiple, credible, sober witnesses. The involvement of the RCMP, the Coast Guard, and the Navy lends it significant weight. Objectively, an event occurred. The foam is particularly interesting. From an investigative standpoint, a physical trace that cannot be collected is a frustrating paradox. It suggests a material with properties we don't understand. However, the lack of any recovered physical wreckage is the critical missing piece. It means we are left with testimony and a transient environmental effect. What does the evidence actually show beyond that? The official conclusion from the Canadian Department of National Defence was, and I'm quoting here, "unresolved." They ruled out aircraft, flares, and celestial bodies. They had no explanation. You mentioned a pattern earlier. There were other reports that night, weren't there? An Air Canada pilot reported unusual lights tracking his aircraft over Quebec just an hour before the Shag Harbor event. Were these sightings ever officially linked, or is that just speculation based on timing?
CASEY RIVERS: That’s exactly where this goes from a strange local incident to a global phenomenon, Jordan. The official file never linked them, but the circumstantial evidence is powerful. This idea of an object moving through the air and then seamlessly entering the water… that’s what we’re talking about. It’s a capability now being discussed at the highest levels of the Pentagon: transmedium travel. Think about it: an object that can operate with equal proficiency in two completely different physical domains—air and water. We have nothing that can do that. A plane hitting water at speed disintegrates. A submarine breaching the surface like a missile is science fiction. Yet, the testimony from highly credible military witnesses in recent years describes exactly this. Former Navy pilot Ryan Graves, who has testified before Congress, has spoken about his squadron encountering these phenomena daily. He describes dark gray or black cubes inside clear spheres, flying at supersonic speeds, stopping on a dime, and then plunging into the ocean without so much as a splash. They’d track them on radar descending from 28,000 feet to sea level in seconds, then continue being tracked underwater. This isn't folklore; this is documented data from some of our most advanced sensor systems, observing craft that violate our known laws of physics and engineering.
JORDAN HAYES: Based on what we know from these military reports, the flight and submerged characteristics are consistently anomalous. We're talking about the 'five observables': instantaneous acceleration, hypersonic velocities without signatures like sonic booms, low observability, transmedium travel, and what they call 'positive lift'—the ability to operate without any visible means of propulsion or aerodynamic surfaces like wings. These are not drones from a rival nation, and they are not conventional aircraft. The fact that the U.S. Navy and the Department of Defense's AARO office now officially use the term 'Unidentified Anomalous Phenomena' to specifically include USOs is a massive shift. For decades, the focus was always on UFOs, on objects in the sky. The idea of objects in the water was often dismissed or ignored. I mean, USO investigations were, and arguably still are, criminally overlooked compared to their aerial counterparts, despite the testimony from naval personnel being just as, if not more, compelling. It moves the entire conversation. What if these objects aren't just 'visiting' from somewhere else? What if they are already here, using the deep, dark, high-pressure environment of our own oceans as a base of operations, or simply as a convenient, hidden highway? The implications of that are profound.
JORDAN HAYES: Profound is one word for it. From an investigative perspective, it’s a logistical nightmare. The sheer scale… we're talking about an environment where evidence, if any exists, is almost impossible to retrieve. Objectively, the pressure, the salinity, the currents—any physical trace would be degraded or gone in an instant. It makes solving a cold case on land look like a walk in the park.
CASEY RIVERS: But that's the whole point, isn't it? That environment isn't just a hiding place; it's a fortress. The darkness down there is absolute, a blanket so complete that our most powerful lights are just pinpricks. And the pressure we mentioned… it’s not just a force, it’s a constant, crushing presence that erases things. It’s the perfect shield. I mean, if you were an advanced intelligence and you wanted to operate on a planet without being constantly bothered by the noisy surface-dwellers, where else would you go? You'd go to the one place their physics and their biology simply break down.
JORDAN HAYES: Let's examine the facts we do have, though. We have the transmedium UAP reports—objects observed moving between air and sea. But what about phenomena that are exclusively submerged? Are there documented cases of objects that are only ever detected deep beneath the surface, operating completely independently of anything happening in the atmosphere?
CASEY RIVERS: Oh, there are. And that’s where the testimony gets even more specific and, you know, more unsettling. We're moving beyond a blip on a FLIR camera that splashes down and vanishes. Here's the thing... we're about to get into accounts from naval sonar operators—people whose entire career is dedicated to interpreting the acoustic world of the deep—tracking anomalies that defy all known signatures. They're detecting objects moving at speeds and executing maneuvers that should be impossible for any submersible we know of, ours or anyone else's.
=== PART 3 ===
CASEY RIVERS: That’s the perfect entry point, because this is exactly where the work of a brilliant, and I think deeply misunderstood, biologist named Dr. Ivan T. Sanderson becomes essential. Sanderson was a Scottish-born zoologist, a Cambridge and Yale man, who spent his life in the field. He was a naturalist in the classic tradition of Darwin, an observer of the highest caliber. But he also had this incredible open-mindedness that allowed him to look at data sets that other academics would simply dismiss out of hand. In 1970, he published a book that, frankly, should be required reading for anyone interested in this topic. It’s called 'Invisible Residents'. And in it, he lays out a hypothesis that is staggering in its scope. Sanderson, after reviewing hundreds upon hundreds of reports—naval logs, pilot debriefings, mariner testimonies stretching back over a century—began to see a powerful, undeniable pattern. He saw that these anomalous phenomena weren't just randomly splashing down into the water. The interactions were too frequent, too specific. He documented cases where these objects seemed to be performing deliberate actions in relation to the water. It wasn't just a convenient place to hide from radar. He posited that the water itself was fundamental to their operation. The way they moved, the way they appeared and disappeared, their seeming mastery of the aquatic environment suggested to him that we weren't looking at visitors who just discovered the ocean. We were looking at something that had a profound, intrinsic connection to it. As if the deep sea wasn't just a temporary shelter, but perhaps their primary domain, maybe even their source of energy.
JORDAN HAYES: Okay, let's look at the language there. "Profound, intrinsic connection." That's a very significant claim. Objectively, what does the evidence show that led him to that conclusion? I understand seeing a pattern of objects entering water, but that's a long way from theorizing an entire civilization that belongs there. A modern nuclear submarine spends ninety-nine percent of its operational life submerged. It enters and exits water. It operates with a mastery of the aquatic environment. We wouldn't look at a foreign sub and conclude it's a non-human intelligence that uses the ocean for power. So, what was the specific, distinguishing factor in the reports Sanderson analyzed? What was the behavioral anomaly that made him say, "This is not ours, this is not a foreign power's, this is something else entirely"? Was he looking at the flight and submerged characteristics we discussed earlier, or was there something more? Because drawing a line from "unidentified craft interacts with water" to "aquatic-based intelligence" requires a substantial body of evidence that rules out more conventional, if advanced, technology. What was the lynchpin for him?
CASEY RIVERS: That is the perfect question, and it's the one that Sanderson himself spent his career trying to answer. The lynchpin for him wasn't just one thing; it was the totality of the circumstances, the sheer strangeness that defied even advanced conventional explanations. And this brings us to the absolute core of his theory, and frankly, this is the part that still gives me chills. He didn't just call them USOs. He coined a new term: OSINs, which stands for Other Submarine Intelligences. And here is the dramatic part, Jordan. He proposed that these intelligences were not extraterrestrial. They weren't coming from Alpha Centauri or some distant galaxy. Sanderson's hypothesis was that they are a highly advanced, non-human, technological civilization that is indigenous to the planet Earth. He believed they evolved here, or have been here for millennia, coexisting with us in secret. And their home, their fortress, is the one place we can barely touch: the deep ocean. The abyssal plains. The crushing pressure, the absolute darkness, the near-freezing temperatures—we see those as hostile barriers to life. Sanderson theorized that for them, it's just... home. It's the perfect environment for a civilization that wishes to remain unseen. He sometimes called them 'OINTS', for Other Intelligences. He speculated that these beings are the architects of the transmedium phenomena, that the UFOs we see are potentially just their equivalent of scout ships, briefly leaving their deep-sea realm to observe the surface world, to observe us, before returning to the safety of the abyss. What if the great mystery isn't about who is visiting us from the stars, but who has been living right alongside us, in an environment we've only just begun to scratch the surface of? Let that sink in. A parallel civilization, right here.
CASEY RIVERS: And to answer your earlier point, Jordan, he did provide a taxonomy of the behaviors that led him to this conclusion. This wasn't just a vague feeling. He meticulously documented specific categories of encounters. For instance, he collated dozens of reports, many from military sources, of disc-shaped or cylindrical objects hovering silently just feet above the ocean's surface. In some of these cases, witnesses described seeing tubes or probes extending from the craft down into the water, almost like a straw, sometimes for extended periods. What were they doing? Refueling? Discharging waste? Taking on biological samples? We don't know, but it’s a deliberate, mechanical interaction. Then there were the accounts of "plungers"—objects seen entering the water at impossible velocities without a splash, or with minimal disturbance, a characteristic that defies physics as we know it. He also heavily documented what he called "submersibles"—luminous, often green or blue lights, tracked on sonar moving at hundreds, sometimes thousands of knots beneath the surface, performing right-angle turns that would pulp any human pilot and tear apart any known vessel. These weren't just blips; they were often corroborated by visual sightings of glowing shapes moving under the waves. He even went back through historical records, looking at old maritime logs from the 18th and 19th centuries, re-examining accounts of "phantom ships" or bizarre, fast-moving "sea monsters" that glowed. Through his lens, these weren't folklore; they were pre-industrial encounters with the same OSIN phenomenon. He was building a profile of an intelligence that has operated with impunity in our oceans for a very, very long time.
CASEY RIVERS: And now, here is where it gets really interesting in a modern context. When Sanderson was writing in 1970, the idea of a complex biosphere in the deep ocean was still largely theoretical. But today? Our entire understanding of biology is being rewritten by what we’re finding down there. We've discovered entire ecosystems, the extremophiles, thriving around hydrothermal vents in complete darkness, under pressures that would instantly crush our best submersibles. We have found life that breathes sulfur. These discoveries prove that life is infinitely more adaptable and resilient than we ever imagined. If a microbe can evolve to thrive in those conditions, is it really such a stretch to consider that a technological intelligence could as well? The scientific basis for a deep-ocean habitat is, you know, exponentially stronger today than it was in Sanderson’s time. But he took it a step further. He also mapped out what he called the "Vile Vortices." He identified twelve specific, symmetrically distributed zones around the globe where anomalous phenomena are statistically concentrated. The most famous are the Bermuda Triangle and the Devil's Sea, south of Japan. But there are ten others. These are areas notorious for magnetic anomalies, navigational failures, and a hugely disproportionate number of ship and plane disappearances. They are also hotbeds for USO and UFO sightings. Sanderson didn't think this was a coincidence. He theorized that these vortices might be the primary entry and exit points for these OSINs, perhaps acting as natural energy wells or even stable wormholes connected to their deep-sea bases. It's a breathtaking idea. What if these legendary danger zones on our maps aren't just quirks of geology, but are actually signposts? The doorways to a world hidden within our own.
CASEY RIVERS: Sanderson's OSINs theory, you know, it challenges us to look beyond the surface—not just of the ocean, but of our own assumptions about what constitutes life and intelligence on this planet. It’s a radical idea, yes, but one that continues to resonate as we keep discovering that the map of life is far stranger than we ever believed.
JORDAN HAYES: Objectively, it’s a framework that attempts to connect disparate anomalous data points. The Vile Vortices map is a fascinating piece of data visualization, whether you accept his conclusion or not. He's drawing lines between documented disappearances, strange energy readings, and areas of high magnetic anomaly.
CASEY RIVERS: Right. And it leads to this profound question. If these intelligences are indigenous, if they’ve been here all along, co-existing with us from the darkness down there, what stories might they have inspired in the cultures that lived closest to the sea? We have millennia of maritime history. Surely, we wouldn't be the first to notice them. What if their legends, the ones about powerful beings rising from the depths, weren't just cautionary tales about storms and sea monsters? Next, we'll explore how ancient myths and cultural narratives might echo these very ideas, suggesting humanity has been grappling with the concept of 'invisible residents' for a very, very long time. Don't go anywhere.
=== PART 4 ===
CASEY RIVERS: We've been talking about the sheer, crushing reality of the deep sea, and Sanderson's hypothesis that a technological civilization could exist down there. But if they have been our neighbors this whole time, surely some trace of them would have trickled into our oldest stories. It turns out, that’s exactly what we find. Across the globe, separated by thousands of miles and thousands of years, cultures have told stories of intelligent beings emerging from the water. These aren't just tales of sea monsters. These are stories of teachers, of civilizers. The Dogon people of Mali, for instance, have a tradition centered on the Nommo. They describe them as amphibious, fish-like beings who came from the sky in an ark, landed in water, and brought profound knowledge to humanity—agriculture, language, the very foundations of their cosmology. They were seen as instructors. Then you look to ancient Mesopotamia, thousands of years earlier. The texts speak of the Oannes, a being described as having the body of a fish, but with a human head and feet beneath the fish's head and tail. Each day, he would rise from the Persian Gulf to teach humanity the arts of civilization: writing, law, architecture. And at night, he would return to the depths. It’s a striking parallel. And of course, these are just two of the most specific examples. We have the ubiquitous mermaid and merman traditions all over the world, from the seductive, dangerous sirens of Greek myth to the powerful and often benevolent Mami Wata spirits of West and Central Africa, who could grant wealth and spiritual wisdom. What if these aren't just fanciful tales spun by sailors? What if they are the distorted, mythologized memories of something far more real? A cultural echo of contact. These narratives all share this incredible commonality: advanced beings, deeply connected to the water, appearing to guide or fundamentally influence human development.
JORDAN HAYES: Casey, it is fascinating how these stories resonate across cultures that had no contact with one another. The parallels are definitely intriguing. But let's look at this from another angle. Is it not more probable that these are simply universal human archetypes? A manifestation of the collective unconscious, as Carl Jung might have put it. We have a fundamental desire for guidance, for a higher source of knowledge, and a deep-seated fear and respect for the unknown. The ocean, being the largest, most powerful, and most mysterious environment on our planet, would naturally become the canvas for such narratives. We have always looked to the sky and the sea and filled those voids with gods and monsters to explain phenomena we couldn't comprehend. Powerful waves become the wrath of Poseidon; a bountiful harvest after a flood becomes a gift from the river god. These stories could be a psychological mechanism for coping with the overwhelming power of nature, not a record of actual encounters. Based on what we know of human psychology, creating 'teacher' figures from the great unknown is a very common trope. So, what does the evidence show for a common origin for these myths, beyond our shared psychological architecture? Is there anything more tangible than the stories themselves?
CASEY RIVERS: That is an entirely fair and necessary question, Jordan. And for a long time, the answer was no. But that's changing. While many of these 'water people' myths absolutely live in the realm of folklore, the core idea—of an advanced civilization hidden beneath the waves—isn't entirely without a parallel in the physical world. Just look at the enduring power of the Atlantis myth. Plato's account, whether you read it as allegory or a fragment of lost history, has captivated humanity for centuries. It speaks to a powerful, almost primal intuition that something significant could be lost down there. For the longest time, it was dismissed as pure fantasy, a philosophical fable. But what if the *idea* of it, the concept of a great city lost to the ocean, isn't so far-fetched? Because, you know, we have actually found them. Archaeological discoveries in the last few decades have confirmed the existence of several real, complex ancient cities now submerged beneath the sea. These aren't myths; they're documented sites. Take Pavlopetri, off the coast of southern Greece. It dates back 5,000 years. It’s one of the oldest submerged cities ever found, complete with streets, buildings, courtyards, and even tombs. We're talking about a planned city from the Bronze Age, now resting under about 12 feet of water. Then there's the incredible discovery of Thonis-Heracleion, off the coast of Egypt. For centuries, it was known only from ancient texts. Now, we've found it. This was a major port city, the gateway to Egypt, that succumbed to a combination of rising sea levels and seismic activity and sank around the 8th century AD. Divers have uncovered colossal statues of pharaohs and gods, dozens of sunken ships, gold coins, and the remnants of the grand temple. These are tangible, documented facts. They prove that entire, sophisticated human civilizations can be swallowed by the ocean and effectively vanish from history, only to be rediscovered millennia later. It makes you wonder what else might be down there, doesn't it?
CASEY RIVERS: So, if we accept that complex cities can be lost to the waves, and we acknowledge that humanity has, for millennia, consistently imagined intelligent life residing in those same oceans, what does that tell us? From an anthropological view, these narratives are more than just random stories. They are too consistent, too specific. They speak to a profound and persistent human intuition about the sea. What if these stories aren't just psychological projections, as you suggested, Jordan? What if they are, as some theories suggest, the only way our ancestors could interpret genuine, unexplained phenomena? Think about it. A transmedium vehicle emerging from the water, like the one described at Shag Harbor, would be utterly incomprehensible to an ancient fisherman. How would you describe it? A fiery chariot from the sea? A glowing god? And this is where it gets truly intriguing, and I think we have to just… buckle up for this idea. What if these myths are the echoes of ancient encounters? Not with gods, not with spirits, but with an indigenous, non-human intelligence that has co-existed with us, sharing our planet from the darkness down there. I mean, this isn't about little green men from another star. This is the core of the crypto-terrestrial idea. The possibility of a civilization so ancient, so perfectly adapted to the crushing pressure and the cold, that their rare, perhaps accidental, interactions with the "surface dwellers" became the very foundation of our legends about sea-gods and water-spirits. The dramatic-reveal here isn't that the myths exist; it's that they might be a form of distorted history, a record of contact seen through the only lens our ancestors had.
JORDAN HAYES: That is a significant leap, Casey. A truly fascinating one, but a leap nonetheless. To go from ancient myths and documented submerged human cities to a conclusion of 'ancient encounters with unseen aquatic civilizations' requires connecting several dots with speculative lines. While the idea is compelling, we must consider the mechanisms of interpretation and misinterpretation. Humans are, fundamentally, pattern-seeking creatures. It's an evolutionary advantage. We see faces in clouds, constellations in the stars, and we create elaborate narratives to explain the things we don't understand. So, couldn't these 'unexplained phenomena' that you're positing as contact simply be natural occurrences? The ocean is filled with bizarre and poorly understood phenomena that would seem magical to ancient peoples. Think about massive blooms of bioluminescent algae lighting up the sea at night, the strange and powerful sounds that travel for hundreds of miles through the SOFAR channel, or even rogue waves and strange whirlpools that seem to defy logic. Lacking a scientific framework for plate tectonics, bioluminescence, or marine acoustics, attributing these powerful and mysterious events to intelligent, god-like beings from the deep is a logical conclusion for an ancient culture. A civilization advanced enough to remain hidden for millennia, yet occasionally interacting in ways that conveniently generate these specific myths, would require an extraordinary level of both technological sophistication and operational secrecy. So my question remains: What does the evidence actually show for such interactions, beyond the mythological accounts themselves? Are there any data points that can't be explained by natural phenomena or human psychology?
CASEY RIVERS: And that, Jordan, is precisely where the mystery deepens. You’re asking for a data point that can't be explained away by natural phenomena, and I get it. But what if the data point isn't a sonar ping, but a story? The sheer consistency of the narrative across disconnected cultures, separated by entire oceans and millennia... that itself is a form of evidence, you know? It’s a persistent signal in the noise of human history, a recurring theme that demands our attention.
JORDAN HAYES: Objectively, it is a powerful psychological and cultural phenomenon. A shared archetype projected onto the largest unknown space on our planet. It’s compelling as a study of the human mind, certainly.
CASEY RIVERS: It is. But what if it’s more? Whether these legends are purely symbolic, psychological projections, or distorted memories of genuine encounters, they undeniably point to a persistent human fascination with intelligent life in the ocean. They lay the groundwork for a truly profound question. What if these ancient stories, these echoes from the deep, are not just folklore, but a veiled history? A history not of our interactions with ephemeral gods, but with the "invisible residents" we've touched on, whose advanced nature was simply interpreted through the only lens our ancestors had: myth. What if they hint at a reality far more complex than we've ever dared to imagine?
JORDAN HAYES: So the legends aren't the evidence itself, but a map pointing to where we should be looking.
CASEY RIVERS: A map written in a language we're only now beginning to decipher. And that leads us to where the speculation of the past meets the analysis of the present. Now here's where it gets interesting… next, we'll explore a modern hypothesis that attempts to bridge this very gap, connecting the dots between ancient myth and contemporary USO observation, suggesting an answer that is, well, closer than we think.
=== PART 5 ===
CASEY RIVERS: So, this is where we get into the Crypto-Terrestrial Hypothesis. And I want to be clear, we are moving beyond established cases into a fascinating, speculative framework that attempts to tie it all together. Forget visitors from other stars for a moment. This hypothesis suggests something far more intimate, and in a way, far more unsettling. It posits the existence of an advanced, non-human intelligence that is indigenous to Earth. A civilization that could have evolved right here, alongside us, but on a completely separate path, remaining hidden for millennia. The theory suggests that this civilization, which might not even be carbon-based in a way we recognize, found its cradle and its sanctuary in the one place on Earth that could offer perfect isolation: the deep ocean. We’ve talked about the pressure, the darkness, the sheer scale of it all. It’s a world within our world, a realm so vast and inaccessible that our best submersibles are like frail little fireflies in an infinite night. This environment could easily conceal entire cities, entire societies, for eons. It’s the ultimate cloak of invisibility. So, this isn't just a flight of fancy. It’s a logical extension when you consider the unexplained phenomena we’ve discussed. It offers an alternative to the extraterrestrial narrative that, for many of these cases, seems to fit the data much more elegantly. It completely reframes the central mystery of the UAP phenomenon. The question stops being, 'Who is visiting us from out there?' and becomes, 'Who is already here, down below?'
JORDAN HAYES: Okay, Casey, I'll grant you it’s a compelling intellectual exercise. It neatly sidesteps a lot of the logistical problems of interstellar travel. But let's examine the facts here. This idea of a separate but congruent existence. If a technological civilization has been developing for thousands, maybe millions of years in the deep ocean, how could it remain entirely separate? We have laid transatlantic cables. We perform deep-sea drilling. We have mapped significant portions of the seafloor with sonar. Objectively, you would expect some kind of undeniable artifact to be found. A tool, a structural fragment, some kind of technological emission that we would pick up. We find ancient Roman shipwrecks, so why not evidence of a civilization far older and more advanced? And beyond that, what's the motivation for such absolute secrecy? It implies a level of psychological and sociological development where they have made a conscious, collective, and perfectly executed decision to avoid us for their entire history. That suggests they know all about us, but have chosen complete isolation. That’s a massive assumption about their psychology. What does the evidence show that points specifically to an indigenous, hidden intelligence, as opposed to just a series of unexplained events involving advanced, but perhaps uncrewed, technology from an unknown origin?
CASEY RIVERS: That is the perfect question, Jordan, because the evidence isn't in artifacts buried in the mud, but in the performance of the objects themselves. This is where the anomalous capabilities of Unidentified Submerged Objects become the central pillar of the hypothesis. As we've touched on, these are not just blips on a screen. These are credible sightings, often documented by highly trained U.S. Navy pilots and sonar operators, people whose entire career depends on identifying what is in the air and in the water. They describe objects demonstrating true transmedium travel. We are talking about a craft moving at hypersonic speeds in the atmosphere, then entering the ocean without creating a splash, without losing any momentum, and continuing on its path as if the water offered zero resistance. The official reports mention speeds and maneuvers that are simply impossible for our technology. Instantaneous acceleration, right-angle turns at thousands of miles per hour, and the ability to operate from the surface all the way down to depths our most advanced military submarines cannot reach. These aren't just anomalies; they are demonstrations of a technology that has mastered a completely different set of physics. If you evolved in a high-pressure, fluid environment, your technology wouldn't be based on aerodynamics and combustion. It would be based on manipulating pressure, density, maybe even the fabric of spacetime itself. So, these USOs, these impossible objects, could very well be their vehicles. They are the echoes from that hidden world, the brief, stunning glimpses of a technology so far beyond our own it appears magical. The dramatic reveal here is that the USOs aren't the mystery to be solved. They might be the answer. They are the calling cards of an intelligence that has mastered the abyss.
CASEY RIVERS: And this brings us to a really profound what-if moment. What if these USOs are just the most visible aspect of a complete 'breakaway civilization'? A branch of intelligent life that chose a different evolutionary path entirely. A society that developed in the crushing blackness of the abyssal plains. Their entire technological and biological reality would be alien to us. Their power sources wouldn't be fire or fossil fuels; maybe they harness the immense energy of geothermal vents, or manipulate quantum fields to draw power from the vacuum. Their sensory world would be completely different. Forget sight as we know it. Their perception might be based on hyper-advanced sonar, intricate patterns of bioluminescence that function as a language, or even forms of electromagnetic communication that pass through water as easily as our radio waves pass through the air. Their 'cities' might not be static structures of metal and stone, but vast, living, bioluminescent habitats integrated into the walls of canyons or built around the hydrothermal vent ecosystems we're just now discovering. Their technology would be an extension of that environment, allowing them to navigate the crushing pressures with ease. And occasionally, perhaps for resources, perhaps for reconnaissance, or maybe just out of simple curiosity, they interact with our world, the surface world. And those interactions are what we perceive as anomalous USO activity. This hypothesis suggests the phenomena we track aren't visitors from Alpha Centauri, but are our neighbors. A highly evolved, ancient, indigenous intelligence that has simply chosen a path of deep separation, thriving in Earth’s most hidden and challenging domain.
JORDAN HAYES: What this hypothesis ultimately does, Casey, is force a confrontation with our own deeply ingrained anthropocentrism. As a species, we define intelligence through a mirror. We look for language, tool-making, and societal structures that resemble our own. We assume any advanced civilization would follow a similar technological trajectory: fire, metallurgy, electronics, space travel. But what if intelligence evolved in an environment completely devoid of light, where pressure is a thousand times what it is on the surface? A civilization that communicates through modulated frequencies in the water, or complex light patterns. Their technology might be more biological than mechanical, an extension of their own physiology, something grown rather than built. It’s interesting, you know, AARO, the Pentagon's All-domain Anomaly Resolution Office, has been very specific in its public statements. They have repeatedly said there is no verifiable evidence of extraterrestrial technology. But the crypto-terrestrial hypothesis doesn't contradict that at all. In fact, it aligns with it perfectly. It suggests we're looking in the wrong place. We're scanning the stars for visitors, when the 'other' intelligence might be terrestrial. This reframes the entire UAP and USO discussion. It asks us to seriously consider that the most advanced intelligence on Earth might not be human. And it might have evolved under conditions so extreme, so utterly alien to our own experience, that its existence is simply beyond our current capacity to easily detect or comprehend. It’s about expanding our definition of 'life' and 'civilization' itself. And it is, objectively, a very humbling thought, to consider we might be sharing our planet with a technological intelligence far older than our own.
The Ocean's Hidden Depths
CASEY RIVERS: As we wrap up this part of our journey, let's just sit with the sheer scale of this idea. We've established that the deep sea is this vast, unmapped frontier. The pressure, the darkness… it's a realm that feels more alien than the surface of Mars. The crypto-terrestrial hypothesis takes that reality and proposes that this isn't just an empty wilderness. It's a plausible sanctuary. It posits that an advanced, non-human technological civilization could have evolved and thrived right here, in Earth's abyssal plains and trenches, completely hidden from us.
JORDAN HAYES: It’s the ultimate blind spot.
CASEY RIVERS: Exactly. It completely re-frames the conversation. We're no longer just scanning the stars. It challenges our entire perception of who we are and, more importantly, who else might be sharing this planet with us.
Shag Harbor's Aquatic Anomaly
JORDAN HAYES: And let's look at the facts that give this hypothesis traction. The testimony, while compelling, is one thing, but the patterns are another. Take the Shag Harbor case we discussed. You have multiple, independent, sober witnesses. You have official military and law enforcement involvement. But the key anomaly is the object's behavior. It demonstrated flawless transmedium flight, moving from the air into the water without any impact, any change in speed. It operated seamlessly between two completely different physical environments.
CASEY RIVERS: A capability we still can't replicate.
JORDAN HAYES: Not even close. What does the evidence show? Objectively, it shows a technological presence in our waters that defies our known physics. It points to something down there with incredible capabilities.
Ancient Echoes, Modern Theories
CASEY RIVERS: Right. And those data points are what give a framework like Dr. Ivan T. Sanderson's OSINs theory so much weight. He wasn't just speculating wildly; he was cataloging these cases, suggesting an indigenous aquatic intelligence was the most logical source. But this idea, you know, it has echoes that go back so much further than the 20th century. When you look at ancient myths from cultures separated by oceans and millennia—the Dogon's Nommo, who were said to be amphibious beings bringing knowledge from the water, or the Japanese Kappa, the water spirits—you see a recurring theme.
JORDAN HAYES: Beings from the deep.
CASEY RIVERS: Precisely. Beings from the deep, often possessing advanced knowledge or strange abilities. What if these aren't just fanciful tales? What if they are fragmented memories, cultural interpretations of genuine encounters with these "invisible residents" that Sanderson theorized about?
The Unseen Neighbors
JORDAN HAYES: So the hypothesis suggests we're not just finding new species and bizarre ecosystems down there, but potentially a civilization that predates our own. Based on what we know of the timeline, that’s a humbling thought.
CASEY RIVERS: It’s profoundly humbling. The Crypto-Terrestrial Hypothesis isn't just another UFO theory; it's an invitation to expand our consciousness, to look at our own world with entirely new eyes. It suggests that the echoes from the abyss, the anomalous craft that operate without any visible means of propulsion in our skies and seas, might not be from distant stars at all. They might be the products of our unseen neighbors, living in the profound, crushing darkness where our most powerful lights barely penetrate. What if the greatest mystery of intelligent life isn't out there in the cosmos, but right here, beneath our feet? What if, in that darkness, life found a way not just to thrive and evolve, but to surpass us technologically and perhaps intellectually? The implications are staggering. It forces us to reconsider everything we thought we knew about Earth, about intelligence, and about our place in this vast, mysterious universe.
CASEY RIVERS: The crypto-terrestrial hypothesis truly challenges us to consider we might be sharing our planet. Join us next time as we continue to peel back the layers of the terrestrial UAP enigma, exploring cases and theories that bring the phenomenon even closer to home. Until then, keep looking up... and perhaps, down. This has been Casey Rivers.
JORDAN HAYES: And Jordan Hayes.
CASEY RIVERS: For 'Closer Than We Think'.
