In 2017, astronomers discovered something they had never seen before: an object from another star system passing through our own.

It was named ‘Oumuamua.

At first, it seemed like an unusual asteroid. But then things became stranger. Its brightness changed dramatically, it appeared to tumble through space, it showed no obvious comet tail, and scientists discovered that something was giving it a small extra push as it moved away from the Sun.

Most researchers believe ‘Oumuamua was a natural object. But Harvard astrophysicist Avi Loeb raised a much more controversial possibility: could it have been artificial technology, perhaps something similar to a light sail?

In this episode, we explore the full ‘Oumuamua mystery — from its discovery and strange behavior to the alien technology hypothesis, the scientific criticism, and the natural explanations that followed.

So what really passed through our Solar System?

A strange object from another world… or something built by one?

Why did the Moon ring like a giant bell?

During NASA’s Apollo missions, astronauts deliberately crashed spacecraft components into the lunar surface while seismometers listened to the resulting vibrations. What scientists recorded helped reveal something remarkable about the Moon’s interior — and eventually inspired one of the strangest ideas in modern alternative history:

What if the Moon is hollow?

In this episode of Lost Civilizations: Ancient Aliens & Forgotten History, René explores the story behind the Apollo seismic experiments, the famous descriptions of the Moon “ringing like a bell,” and the theories that grew from them.

Could unusual lunar vibrations simply be the result of the Moon’s dry, fractured geology? Or is there something about our closest celestial neighbor that we still don’t fully understand?

We explore the Apollo experiments, moonquakes, lunar geology, the origins of the Hollow Moon theory, claims that the Moon could be artificial, and the arguments both for and against these extraordinary interpretations.

The goal isn’t to tell you what to believe.

It’s to separate what we know, what we think we know, and what remains unexplained — and let you decide where the evidence leads.

In 1977, a radio telescope in Ohio detected a signal from deep space so unusual that astronomer Jerry Ehman circled the data in red ink and wrote one word beside it: WOW!

The signal lasted just 72 seconds. It was extraordinarily strong, narrowband, and appeared near the hydrogen line—a frequency scientists had suggested an intelligent civilization might use to contact us. But the signal was never detected again.

For nearly 50 years, the Wow! Signal has remained one of astronomy’s greatest mysteries. Was it an unknown natural phenomenon, interference, or possibly a transmission from another civilization?

Now, researchers have reanalyzed the original data and proposed a new explanation involving cold hydrogen clouds and an extremely rare cosmic event, potentially triggered by a magnetar.

But the hypothesis is controversial, and other scientists argue that the physics behind it has never been observed.

So what really happened during those 72 seconds in 1977?

Göbekli Tepe is one of the most extraordinary archaeological discoveries ever made. Built more than 11,000 years ago by hunter-gatherers, it challenges long-held assumptions about the origins of civilization.

But does it really prove the existence of a lost advanced civilization?

In this episode, we separate evidence from speculation as we explore the claims of Graham Hancock, the Younger Dryas impact hypothesis, Pillar 43, Atlantis, Ancient Apocalypse, and the latest wave of AI-generated videos claiming to have “solved” the mystery. We examine what archaeologists have actually discovered, what remains uncertain, and why Göbekli Tepe has become the center of one of the biggest debates in archaeology.

From groundbreaking excavations to viral conspiracy theories, this is a deep dive into one of humanity’s oldest and most fascinating monuments.

How much do we really know about our distant past—and how much are we simply filling in with stories?

Watch now and decide for yourself.

For more than 50 years, one question has refused to disappear: How did the Apollo astronauts survive the Van Allen radiation belts?

The debate exploded again after a 2014 NASA video showed engineer Kelly Smith saying, “We must solve these challenges before we send people through this region of space.” To many skeptics, those ten seconds became evidence that the Moon landings could never have happened. Filmmaker Bart Sibrel has used this clip for years as one of his strongest arguments against NASA’s official story.

But does the quote actually mean what people think it means?

In this episode, we examine the complete context behind the famous clip, the physics of the Van Allen belts, Apollo radiation data, James Van Allen’s own response to the conspiracy theory, independent scientific analyses, and the impact of the historic Artemis 2 mission. We also fairly present Sibrel’s strongest arguments before comparing them with the available evidence.

This isn’t about telling you what to believe. It’s about following the evidence, separating documented facts from speculation, and asking whether the full picture supports—or challenges—the most famous Van Allen argument against the Moon landings.

In this episode, we're heading straight to the bottom of the North Sea — literally. About 8,000 years ago, a rich, forested landmass sat right here, bigger than many of today's European countries. It used to have no name at all, because nobody knew it had ever existed — today we call it Doggerland.

We start with a fishing trawler that, in 1931, hauled up a 13,000-year-old harpoon from the seabed, and we follow the trail through geologists, archaeologists, and DNA researchers who've slowly pieced together an entire vanished landscape.

Along the way, we'll hit a massive tsunami out of Norway, a Stonehenge made of deer skulls, a man with blue-green eyes and dark skin from a cave in Somerset, and a French pseudo-documentary about an "Atlantean city" on the seafloor — which we're about to debunk.

And at the very end, we'll ask the big question: if Doggerland really did drown an entire civilization, why don't we have any myths about it — unlike Atlantis, which never existed at all?

On July 20, 1969, Neil Armstrong set foot on the Moon — or did he?

For more than fifty years, a global conspiracy theory has claimed the entire Apollo program was a staged deception, filmed on a soundstage to win the Cold War against the Soviet Union. This episode draws on an extensive body of material — 30 YouTube documentaries and interviews in English, French, Spanish, Portuguese, and Russian — from Bart Sibrel's confrontations with astronauts to Russian physicists' technical counterarguments.

We walk through the classic "evidence" (the flag, the missing stars, the shadows, the radiation belt, the missing crater), the more exotic side trails (murder theories, Kubrick, Freemasons), and hold them up against NASA's own measurement data, independent spacecraft from four other nations, and half a century of physics.

The goal isn't to declare a winner — it's to show where the line actually falls between a good story and a documented fact.

What if everything we think we know about Baalbek is incomplete?

Hidden beneath one of the Roman Empire’s greatest temples are stone blocks weighing up to 800 tons—while an even larger 1,650-ton monolith still rests in the nearby quarry, never moved. How was this possible? And who really built the massive platform beneath the Temple of Jupiter?

In this episode, we investigate the evidence, from Roman engineering and archaeological discoveries to the latest LiDAR scans and AI-assisted research. We also examine the controversial claims surrounding lost civilizations, Graham Hancock’s theories, and whether the facts support these extraordinary ideas.

Could the Romans really move stones of this size? Was there an older structure beneath the temple? Or is Baalbek simply the greatest engineering achievement of the ancient world?

Join us as we separate fact from fiction and explore one of archaeology’s biggest unsolved mysteries—a place that continues to challenge historians, engineers, and archaeologists more than 2,000 years after it was built.
