Episodes

Walking Amogus 16.06.2026

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 conquerors apparently cannot work a toaster, order a coffee, or figure out when to clap at a concert, so they...

The Real Mantis Was The Exploitation We Made Along The Way 09.06.2026

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. This week, Tristan brings on Stanford (yes, the one we verbally abused all of last season, now a guest in...

Rosicrucianism Was Just A 1614 S***post 02.06.2026

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, passed down by the secret Rosicrucian order. Tristan and guest Sarah Davis Baker are here to inform you th...

Nikola Tesla Was Never Forgotten, He Was Just Sad 26.05.2026

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 wrote the dismissive evaluation report was, no joke, John G. Trump, uncle of the current US president....

Tartaria: A Russian Psyop For People Who Hate Drywall 19.05.2026

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 to have made the definitive YouTube video on this exact topic two years ago and then forgot she'd bee...

Leonardo da Vinci Was Just A Guy With ADHD 12.05.2026

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 sketches. Sophie also has a YouTube channel called We Have Always Existed about gender-nonconforming peop...

Anarchist praxis in the 17th century (a love story) 05.05.2026

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 survivors. The actual story is way better: a feudal dynasty extracted so much labour from its people tha...

We Should've Had Shovels For Hands 28.04.2026

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 through the claim piece by piece: the Anunnaki population control panic, the inside-job volcano theory, the...

Struck Down In His Prime At 90 Years Young 21.04.2026

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: batteries, Thailand's impressive colonial-era diplomacy, why calling medieval people historically illi...

The Clearest UFO Photo of 2026 Costs $12 at Party City 26.03.2026

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 President had just promised the alien files were coming. It's a $12 Party City balloon bouquet shaped like a mo...

Magnets: How Do They (Not) Work? 03.03.2026

Ancient Aliens claims the 3,000 standing stones at Carnac in Brittany are quartz-rich geomagnetic batteries that beam GPS signals to extraterrestrials. In this episode, Tristan takes us deeper into the actual physics of magnetism than this podcast has possibly ever gone, and it turns out the Earth's magnetic field is so weak your fridge magnets are millions of times more powerful, quartz can't hol...

Coral Castle: Women Always Be Wanting You To Make Megaliths 24.02.2026

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 sprawling stone garden in Homestead, Florida that features astronomical alignments, stone rocking chairs, a...

Scott Is Tired So His Pregnant Wife Is The Host Now 17.02.2026

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 "Armenian Stonehenge." The claim? The 80 holes drilled into these stones are precisely aligned with th...

Sacsayhuamán: The One Where We Solve the Male Loneliness Epidemic 10.02.2026

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 they did it through sophisticated engineering, organized labour systems, and generations of accumulate...

Göbekli Tepe Part 2: Oops, All Tristan Makes You Sad 03.02.2026

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 mad), then spiral into a serious discussion about how recommendation algorithms, economic incentives,...

Göbekli Tepe Part 1: Using Excessive Amounts of Lube To Move Big Rocks 27.01.2026

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 (or at least a visit from some tall, white Atlanteans). In Part 1 of this deep dive, we look at...

3I/ATLAS: Stop Trying To Make 'Oumuamua 2 Happen 20.01.2026

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 is "objectively wrong" and why the reality, a 14-billion-year-old "Universe Placenta" from the dawn of...

The Most Important Rock In History Is Stuck In A Locker On Mars 13.01.2026

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 "leopard spots," which, on Earth, are a chemically specific signature of biological life. We discuss the r...

Tristan Has Watched K-Pop Demon Hunters 6,000 Times 06.01.2026

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 brain). Once we get that out of our system, we open the mailbag to face the music....

Henry Said My Therapist Wants to F*** Me 11.11.2025

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 exploit vulnerable people experiencing mental health crises, turning psychological suffering into profits th...

A Fast Pass To Heaven (Terms and Conditions Apply) 04.11.2025

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, strange history of how Christianity, a religion born from oppressed people, was transformed into a tool for...

I'm Gonna Beat Jesus 28.10.2025

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 angels alike. It’s a theory so powerful that it supposedly dictates everything from ancient history to...

Elf on the Shelf Is A Cop 21.10.2025

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 technology, but a very human one: the invention of divine surveillance as a tool for social control. Join us...

The Gospel According to the House Hippo 14.10.2025

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 actually extraterrestrial visitors misunderstood by primitive humans. Join us as we...

Dramatic_Fart.mp3 07.10.2025

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 biosignature of alien life. But then, as quickly as it appeared, the confidence began to fade. Join Tristan and...
