Episode Guide

Aliens B.C.

Season 10's premiere episode argues that advanced civilizations may have inhabited Earth thousands of years before mainstream timelines suggest, pointing to megalithic monuments, unexplained underground structures, and anomalous artifacts as potential evidence. While the episode description references enormous manmade caves and underwater discoveries, the transcript focuses extensively on crop circles as possible extraterrestrial communication. Ancient astronaut theorist Giorgio Tsoukalos interprets these formations as "messages from elsewhere...of extraterrestrial origin," while investigative reporter Linda Moulton Howe highlights cases like the 2015 Turin, Italy formation that appeared near an airport without detection. The episode notes over 10,000 crop formations have been documented across 50 countries since the 1960s, with researchers emphasizing the absence of footprints or broken stalks in many cases and the sudden explosion of complex designs worldwide after 1990.

NASA's Secret Agenda

This episode asks whether Wernher von Braun, the German aerospace engineer who designed the Saturn V rocket and enabled the Apollo moon landing, had access to secret knowledge beyond conventional science. Ancient astronaut theorists including David Wilcock and William Henry suggest von Braun's extraordinary leap beyond his contemporaries—even geniuses like Einstein and Oppenheimer—may have come from Nazi-collected intelligence, recovered technology from the alleged 1947 Roswell UFO crash, or direct contact with extraterrestrial beings. The episode points to von Braun's eerily accurate predictions in his 1950s Disney collaborations, watched by 42 million Americans, where he detailed space suits, lunar landers, and Mars missions that would later become reality, and questions whether his all-consuming conviction that humanity's future lay in space stemmed from otherworldly influence.

Aliens and Robots

"Aliens and Robots" explores whether humanity's accelerating development of sophisticated androids might be retracing a path already taken by extraterrestrial visitors in ancient times. The episode highlights cutting-edge robotics research at Japan's Advanced Telecommunications Research Institute, where Dr. Hiroshi Ishiguro has created Geminoid robots using over 50 actuators to replicate human facial expressions with uncanny precision, and the University of Texas, where engineers have built Dreamer, a robot capable of whole-body human-like movement. Ancient astronaut theorists like Giorgio Tsoukalos suggest this technology mirrors ancient accounts: Greek myths from 2000 B.C. describe the god Hephaestus creating mechanical servants and the bronze giant Talos, while Egypt's Pyramid Texts recount Osiris being dismembered and reassembled like a machine. The episode asks whether these stories preserve memories of actual robotic beings created by advanced civilizations, and whether the universe's dominant intelligences might themselves be artificial.

Dark Forces

This episode explores the ancient aliens hypothesis that extraterrestrial beings may represent the literal forces of good and evil described across human cultures. Ancient astronaut theorists including Giorgio Tsoukalos and William Bramley propose that entities labeled as demons, Satan, or dark gods in ancient texts—from Mesopotamian deities to Egyptian pantheons—were actually extraterrestrials engaged in a cosmic struggle, with humans serving as pawns. The episode examines historical figures allegedly channeling dark forces: Rasputin, who claimed to serve as a conduit to otherworldly realms; Nazi SS officers purportedly accessing supernatural power through ancient symbols; and occultist Aleister Crowley, who believed he summoned non-human entities through ritual magic. Even serial killers like Richard Ramirez and David Berkowitz claimed external dark entities compelled their violence, raising the question of whether such forces have objective existence beyond human psychology.

The Alien Evolution

This episode explores whether the bewildering variety of non-human entities described in global mythology—from bird-headed gods to blue-skinned deities to multi-limbed beings—might represent different extraterrestrial species that visited Earth throughout history. Ancient Astronaut theorists suggest that the Paracas skulls of Peru, first excavated by archaeologist Julio Tello in 1927, offer physical evidence of such visitors. Researcher Brien Foerster highlights that roughly five percent of these elongated skulls exhibit anomalies beyond mere shape: some are 60% heavier than typical human skulls, possess brain capacities 2.5 times larger than normal, lack the sagittal suture found in all human skulls, and—according to preliminary DNA testing on skull number 44—contain genetic sequences that "didn't match anything known to be human." Theorists argue these remains represent a separate bloodline or hybridization event connecting humanity to otherworldly ancestors.

The Other Earth

This episode explores whether the recent discovery of thousands of potentially habitable exoplanets, particularly Kepler-452b (dubbed "Earth 2.0"), might support ancient astronaut theorists' claims that extraterrestrials visited Earth in our distant past. Ancient astronaut proponents like Giorgio Tsoukalos argue that mythologies worldwide—from the Dogon tribe's belief that their gods originated from the Sirius star system to the Maya's association of deities with the Pleiades cluster and Hopi traditions of celestial beings seeding life—preserve memories of actual contact with advanced beings who themselves once searched for habitable worlds. The episode presents these cultural narratives as potential evidence that extraterrestrials not only visited Earth but may be "responsible for our very existence," drawing parallels between humanity's current search for other Earths and what ancient visitors allegedly did millennia ago.

Creatures of the Deep

When Russian cosmonauts discovered living sea plankton on the International Space Station's windows in August 2014, ancient astronaut theorists saw a profound implication: if Earth's sea life can survive in space, might alien organisms be thriving in our oceans? The episode builds on astrobiologist Chandra Wickramasinghe's panspermia hypothesis—that comets and asteroids seed life throughout the universe—to suggest that legendary sea creatures like the Kraken, Loch Ness Monster, and Japan's child-drowning kappa may be extraterrestrial entities hiding in Earth's waters. Theorists including Giorgio Tsoukalos point to the HMS Challenger expedition of 1872-1875, which discovered abundant life at ocean depths previously thought uninhabitable, and note that two-thirds of Earth's estimated 700,000 to one million marine species remain unidentified. David Wilcock claims some deep-sea creatures possess genes "that don't match up with anything else that we have on Earth."

Circles from the Sky

"Circles from the Sky" investigates the crop circle phenomenon, with Giorgio Tsoukalos traveling to England—a global hotspot for these formations—to examine whether the over 10,000 reported designs worldwide could represent alien communication. Ancient astronaut theorists argue that these patterns, ranging from simple circles to thousand-foot pictograms, contain encrypted mathematical, geometric, and astronomical equations that challenge conventional explanation. Proponents point to reports of scientific anomalies, unexplained lights, and alleged historical precedents stretching back hundreds or thousands of years, suggesting the phenomenon transcends modern hoaxing. The episode positions crop circles as potential messages requiring decryption, with researchers claiming the complexity of certain designs exceeds what anonymous pranksters could achieve overnight.

The Alien Wars

This episode explores whether deliberate destruction of ancient sites in the Middle East—particularly the 2015 ISIS demolition of Nimrud, a 3,000-year-old Assyrian capital near Mosul—might serve an extraterrestrial agenda rather than merely religious extremism. Ancient astronaut theorists, including Giorgio Tsoukalos and David Wilcock, suggest that the systematic erasure of Mesopotamian artifacts and texts could be orchestrated to prevent humanity from discovering evidence of alien visitation. The episode also examines Gary McKinnon's 2002 arrest for hacking Pentagon and NASA systems, where he claimed to find rosters of "non-terrestrial officers" and spacecraft with USSS designations, potentially indicating a secret space program preparing for conflict with alien factions. Theorists argue that ancient accounts of wars between gods may actually document battles between competing extraterrestrial groups on Earth.

The Forbidden Zones

"The Forbidden Zones" examines whether conflict-plagued regions are deliberately kept unstable to prevent archaeological discoveries about humanity's extraterrestrial past. The episode focuses on the 2015 destruction of Nimrud, the ancient Assyrian capital near Mosul, where ISIS militants obliterated 3,000-year-old winged lion statues and Mesopotamian god reliefs before leveling the entire site with explosives. Ancient astronaut theorists including Giorgio Tsoukalos and David Wilcock suggest this destruction—along with widespread looting across Iraq, Syria, Egypt, Tibet, and Central America—may be part of an otherworldly agenda to conceal evidence of alien contact. They point to over 700,000 artifacts stolen or destroyed in the Middle East since 1990 and question whether the region's perpetual instability serves to hide transformative historical truths.
