Was Earth really visited by mysterious extraterrestrial travelers thousands of years ago as many proponents of ”ancient astronaut theory” believe? What are the hidden secrets and mysteries behind ancient monuments and forgotten civilizations? Every week, historian Tristan Johnson and regular human person Scott Niswander dive through the archives to learn about the fascinating histories of ancient civilizations while also debunking the myths and straight-up lies presented in History Channel‘s massively popular tv show Ancient Aliens that has sparked a new generation of conspiracy theorists. We hope through this show, you can gain an appreciation for just how cool ancient societies were, and not simply credit their impressive advancements to alien visitors. NEW EPISODES EVERY WEEK! Follow the show so you don‘t miss an episode, and leave us a review! It really helps us out!
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 the constellation Cygnus as ...
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 accumulated knowledge. We explain th...
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, and media exploitation cre...
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 the actual "dirt science." We...
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 time, is infinitely coole...
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 rigorous science behind the ...
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.
We issue mea culpas for mixing ...
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 through algorithmic radicali...
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 imperial conquest. It's a ...
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 modern warfare.
So, is the ...
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 as we unpack the 5,000-y...
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 dive into the linguistic weeds...
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 Scott as they investigate w...
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 revolutionary new food group known as "pickle fries." The hosts also tackle more serious topics, including a historical correcti...
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 about the correct pronunciation of poutine. This episode features questions from our space potato supporters and includes mult...
Let's explore the bizarre world of the Montauk Project, where recovered memories meet Cold War paranoia to create one of America's wildest conspiracy theories. We explore how a decommissioned military base somehow became ground zero for alleged government experiments in mind control, time travel, and alien contact. We'll examine their "recovered memories" spawned an entire conspiracy industry, and trace the project's influ...
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. From the Morris County sightings to the Coast Guard's encounter with a dozen coordinated drones, we dive into what's really happening, why everyone's freaking out, and how this fits into America's long history of technology panics. Plus, w...
Scott and Tristan melt down Ancient Aliens' claims about Scotland's mysterious vitrified forts. Through terrible Scottish accents and unexpected detours into modern battery technology, they explore how Iron Age Scots used sophisticated fire management techniques to create these unique structures - no alien death rays required. Learn why turning your fort's stones into glass might actually be a terrible defensive strategy, ...
Join us as we dive into one of ancient history's most persistent myths: Archimedes' legendary death ray. From Ancient Aliens' claims of extraterrestrial technology to Mythbusters' multiple attempts to recreate it, we explore how this mathematical genius became associated with a weapon that probably never existed. But don't worry - we'll also discover the actually-awesome Claw of Archimedes, talk about why steampunk deserve...
Was Alexander the Great's historic campaign into India really halted by alien intervention? Ancient astronaut theorists say yes (of course they do), claiming mysterious flying shields scared his war elephants. We dive into the actual historical records, discuss why troops might not want to march through mountain deserts with elephants, and explore how one of history's most influential figures became the subject of pseudohi...
