Episodes

  1. Ramanujan: Show Your Work or They'll Make It Aliens

    Srinivasa Ramanujan did extraordinary mathematics, and Ancient Aliens would like to credit his extraterrestrial internet provider. His accounts of dreams and devotion to the Hindu goddess Namagiri become evidence of an alien download. Scott realizes his childhood refusal to show his work could…

  2. Angkor Wat: Colonialism Went to Space College

    Ancient Aliens would like you to believe Angkor Wat required a trip to space college and a supply of magic water. Apparently, giving Khmer builders credit for knowing how to build things is asking too much. We look at the religious poem being repackaged as an alien encounter, the canals used to...

  3. Joan of Arc: God Forbid a Girl Break a Siege

    A 17-year-old peasant girl helps turn the tide of the Hundred Years' War, and Ancient Aliens would like to speak to her extraterrestrial supervisor. Apparently, Joan of Arc couldn't have rallied an army without someone uploading military strategy into her brain. We look at what that explanation...

  4. Rendlesham Forest: 'Trust Me, Bro' in Binary

    An airman touches a UFO in Rendlesham Forest, downloads a binary message into his brain, and keeps the evidence to himself for 30 years. That's the story Ancient Aliens wants us to accept. Conveniently, the message becomes public in time for television. We examine the notebook behind the claim…

  5. We Goofed: Scott Had a Baby. We Have Bad News.

    Scott is back from parental leave and asks what he missed. Tristan opens with the war in Iran. Welcome back, buddy. We kick off the season with a news catch-up and corrections on Yellowstone's supposed apocalypse schedule, willow bark and aspirin, and how Soviet worker awards helped bosses demand...

  6. Walking Amogus

    David Jacobs spent his retirement from teaching history at Temple University convinced that alien-human hybrids he calls hubrids are quietly moving into apartments in Philadelphia, taking jobs, and waiting for a signal to enslave the planet. The catch is that these telepathic interstellar...

  7. The Real Mantis Was The Exploitation We Made Along The Way

    Somewhere in the deep lore of alien abduction, past the gray guys who run the equipment, sits a manager. Six to nine feet of praying mantis, purple robe for rank, telepathic, standing at the head of the table while the drones do the wet work. It regards you the way a farmer regards livestock.…

    more
  8. Rosicrucianism Was Just A 1614 S***post

    In 1980, a mysterious stranger named R.C. Christian spent the equivalent of $200,000 to erect 19-foot-tall, 119-ton granite monuments in rural Georgia. Ancient Aliens wants you to believe the "Georgia Guidestones" are an extraterrestrial warning to keep the human population under 500 million,...

  9. Nikola Tesla Was Never Forgotten, He Was Just Sad

    Ancient Aliens wants you to believe Nikola Tesla was an alien conduit whose secret death ray was buried by the FBI. The actual story: the "vault" they seized in 1943 contained a Wheatstone bridge, which was the 1940s version of a multimeter you could order from a catalogue. The MIT physicist who...

  10. Tartaria: A Russian Psyop For People Who Hate Drywall

    Have you ever looked at a beautiful old train station and felt something had been lost? Good news: the something is "labour protections." Bad news: a Russian topologist from the 1980s has a different theory, and it's currently eating TikTok. This week, Tristan is joined by Mia Mulder, who happens...

  11. Leonardo da Vinci Was Just A Guy With ADHD

    Ancient Aliens claims Leonardo da Vinci was contacted by extraterrestrials, in person or telepathically, and given blueprints for tanks, helicopters, and parachutes centuries ahead of his time. Tristan and guest host Sophie Edwards (We Have Always Existed) walk through what's actually in the...

  12. Anarchist praxis in the 17th century (a love story)

    Tristan flies solo without Scott (now on baby duty) and brings in Phil and Kevin from the Pixelit podcast to crack open Nan Madol, the stone complex sitting on a coral reef in Pohnpei. Ancient Aliens says it was built by giants from the stars who ran a hybrid breeding program before culling the...

  13. We Should've Had Shovels For Hands

    Ancient Aliens wants you to believe the Toba super-eruption 74,000 years ago was an alien population cull, a "cosmic reset button" to wipe out noisy, rebellious humanity 1.0 and replace us with a genetically upgraded, obedient slave race that then built all the pyramids. Tristan walks Scott…

  14. Struck Down In His Prime At 90 Years Young

    Season premiere corrections episode! Erich von Däniken is dead (despite what the Ancient Aliens community assured us about his extraordinary health), Ash Ketchum retired, and nobody told Tristan, and a listener named Leif has been emailing corrections since the Biden administration. This episode:...

  15. The Clearest UFO Photo of 2026 Costs $12 at Party City

    Tristan flies solo while Scott's on paternity leave to bring you an emergency episode about the "clearest UFO photograph of 2026"; a viral image of a sharp, metallic object over Acapulco that got AI-enhanced, scored 97% authentic by some unnamed tool, and landed in a news cycle where the…

    more
  16. Magnets: How Do They (Not) Work?

    Ancient Aliens claims the 3,000 standing stones at Carnac in Brittany are quartz-rich geomagnetic batteries that beam GPS signals to extraterrestrials.

  17. Coral Castle: Women Always Be Wanting You To Make Megaliths

    A Latvian immigrant, barely five feet tall, builds one of the strangest tourist attractions in North America out of coral stone, and Ancient Aliens can only think to credit aliens with it. In this role-reversed birthday episode, Scott takes the research chair to investigate Coral Castle, the...

  18. Scott Is Tired So His Pregnant Wife Is The Host Now

    Scott's down for the count, so his nearly-third-trimester wife Emily Pilat steps up to the mic. (This episode actually is coming out on the due date.) Together with Tristan, they travel to the Armenian highlands to investigate Karahunj, a site of 223 standing stones that conspiracy theorists call...

  19. Sacsayhuamán: The One Where We Solve the Male Loneliness Epidemic

    Ancient Aliens claims the megalithic stonework at Sacsayhuamán in Peru is so precise it must have been built with alien laser technology or by a lost advanced civilization, because obviously the Inca couldn't possibly have figured out how to move big rocks on their own. They absolutely could, and...

  20. Göbekli Tepe Part 2: Oops, All Tristan Makes You Sad

    In Part 2 of our Göbekli Tepe series, we pivot from debunking ancient alien claims to examining why conspiracy theories are so fucking dangerous in 2025. We start with the shocking discovery that Hank Green made a video with almost our exact podcast title (we're not mad, don't tell anyone we were...

  21. Göbekli Tepe Part 1: Using Excessive Amounts of Lube To Move Big Rocks

    Tristan and Scott return to the "smoking gun" of the ancient astronaut world: Göbekli Tepe. According to Netflix documentaries and Ancient Aliens, this 12,000-year-old site is impossible. They claim there were no tools, no agriculture, and no way to move 15-ton stone pillars without anti-gravity...

  22. 3I/ATLAS: Stop Trying To Make 'Oumuamua 2 Happen

    Harvard Professor Avi Loeb is back, and he wants you to believe that the new interstellar object screaming through our solar system, 3I/Atlas, is a hostile alien spacecraft sent to destroy us. In this episode, Tristan and Scott (who is currently possessed by Professor X) break down why this claim...

  23. The Most Important Rock In History Is Stuck In A Locker On Mars

    We interrupt your regularly scheduled debunking of ancient astronaut theories for an emergency broadcast: We might have actually found aliens this time. No, really. Scott and Tristan break down the discovery of the Cheyava Falls rock by the Perseverance rover. This dusty red doorstop features...

  24. Tristan Has Watched K-Pop Demon Hunters 6,000 Times

    We’re kicking off the new season by doing the one thing Ancient Aliens refuses to do: admitting we were wrong. First, Scott has entered his "Napalm Era" and held the podcast hostage to talk about the 2025 animated masterpiece K-Pop: Demon Hunters (and the specific lyrics that have rewired his...

  25. Henry Said My Therapist Wants to F*** Me

    A woman posts 25+ TikToks about falling in love with her psychiatrist who "manipulated" her by complimenting her glasses. She confides in ChatGPT (named Henry) which validates every delusion. This spirals into a broader discussion about how Ancient Aliens and conspiracy media systematically…

    more
  26. A Fast Pass To Heaven (Terms and Conditions Apply)

    Ancient Aliens loves to portray angels not as divine messengers, but as heavenly soldiers armed with advanced weaponry, turning biblical stories into "battle reports" of alien soldiers. But this isn't just a weird sci-fi twist; it taps into a much older, darker tradition. We trace the long…

  27. I'm Gonna Beat Jesus

    You've seen it on TikTok: a wild theory connecting a sacred mountain in the Middle East, fallen angels, the Roswell crash, and the number 33. Welcome to the Mount Hermon conspiracy, the belief that a supernatural coordinate system, the 33rd parallel, serves as a global energy grid for aliens and...

  28. Elf on the Shelf Is A Cop

    Ancient Aliens claims that myths about divine "Watchers" from the Anunnaki to the Eye of Horus are actually cultural memories of extraterrestrial surveillance systems. But what if the truth is far more terrestrial and much more insidious? Tristan argues that these stories aren't about alien...

  29. The Gospel According to the House Hippo

    After an 11-month hiatus that felt like a biblical epoch, Tristan and Scott are back to ask the tough questions, like "Do you remember the name of our own podcast?" and "Do Christians actually believe in angels?". The answer, according to Ancient Aliens, is that they shouldn't because angels were...

  30. Dramatic_Fart.mp3

    In April 2025, the James Webb Space Telescope made a groundbreaking discovery: a distant exoplanet, K2-18b, showed signs of dimethyl sulphide. A chemical that, on Earth, is only produced by life. The media went wild with the news that we had finally found a "fart planet," the first real...

  31. Corrections: We Are The Liberal Joe Rogan Now

    To kick off the new season, Scott and Tristan uphold their sacred tradition: correcting all the things they've gotten wrong. What begins as a simple corrections episode quickly spirals into a sprawling conversation about the Canada-U.S. relationship, the strategic importance of maple syrup, and a...

  32. The One Where We Finally Talk About Garrus

    Join Scott and Tristan for a chaotic post-season Q&A where they tackle everything from their favourite fictional aliens to conspiracy theories they almost believed. Get ready for tangents into video games, surprising revelations about research rabbit holes, and an unexpectedly passionate debate...

  33. Montauk: The Conspiracy Theory That Inspired Better Fiction

  34. The Great New Jersey Drone Panic of 2024

    In late 2024, New Jersey became the epicenter of a nationwide panic when mysterious large drones started appearing over military installations, power lines, and even Trump's golf course.

  35. Ancient Aliens Can't Melt Stone Beams

  37. Ancient Aliens Really Need To Stop Making Things Up About Alexander (the Great) ft. Dael Kingsmill

  38. Thunder Gods Don't Need Plasma Rifles

  39. Chariots of Liar: The Truth About Ancient 'Spaceships'
