Our Editor's Take

The It's Probably (not) Aliens! podcast wants to debunk myths about extraterrestrial life. The hosts of the show are Tristan Johnson and Scott Niswander. Tristan is a historian and creator of Step Back History, a popular YouTube channel. Scott makes videos on YouTube for NerdSync.

Ancient Aliens is a pseudoscience show on the History Channel. Its premise is that extraterrestrials populated the earth thousands of years ago. According to the show's hosts, many of Earth's wonders are evidence of alien presence. The show taps into existing conspiracy theories while feeding new ones. Scott and Tristan think everything on Ancient Aliens is hogwash. They created this podcast to provide reasonable alternatives to wild theories.

Episodes of It's Probably (not) Aliens! address myths one at a time. There's an episode on the pseudoscientific field of cryptozoology. This is the study of mythical animals like Sasquatch and unicorns. Using Darwinism and historical facts, Tristan and Scott demonstrate the flaws in the belief that dragons are real. The Fermi paradox is the subject of one episode. It establishes the premise that if alien life existed, humans would have made contact by now. The cohosts show the fallacies in Ancient Aliens' claim that Hercules was an alien.

While much of the podcast's purpose is to correct the record, the cohosts have an ulterior motive. Theories about aliens building Stonehenge and the pyramids hide an important truth. The human capacity for performing feats of science and architecture is boundless. Historical facts can be even more astonishing than alien visitors. Tristan and Scott reveal the real wonders by sharing facts and scientific theories with listeners.

It's Probably (not) Aliens! may appeal to listeners who want to back up their skepticism with facts. History enthusiasts might appreciate learning about the ancients in greater detail. The podcast hosts are engaging and funny, besides being knowledgeable.

Montauk: The Conspiracy Theory That Inspired Better Fiction

Montauk: The Conspiracy Theory That Inspired Better Fiction

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 influence on pop culture from The X-Men to Stranger Things.

The Great New Jersey Drone Panic of 2024

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. 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, why you probably shouldn't shoot down any drones, even if they're really annoying you.Get new episodes early and support the show on Patreon and Nebula!Subscribe to It's Probably (not) Aliens for weekly episodes about cool ancient history!

Ancient Aliens Can't Melt Stone Beams

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, why Ancient Aliens should have watched Outlander for better research, and how climate change is threatening these fascinating historical sites.

The Ancient Greek Scientist Who Didn't Build a Death Ray

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 deserved better, and learn how the same principles behind this mythical death ray are now being used to fight climate change.

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

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 pseudohistorical alien theories. Plus, we learn way too much about medieval siege tactics involving hot sand and... other substances.Check out Dael Kingsmill here.Get new episodes early and support the show on Patreon and Nebula!Subscribe to It's Probably (not) Aliens for weekly episodes about cool ancient history!

Thunder Gods Don't Need Plasma Rifles

Thunder Gods Don't Need Plasma Rifles

Ancient Aliens claims that mythological super-weapons - from Zeus's thunderbolts to Poseidon's trident - were actually advanced alien technology misinterpreted by ancient peoples. But what if these legendary artifacts were actually serving a different purpose? Join us as we explore how these weapons represented divine authority, natural forces, and cultural values rather than extraterrestrial tech. We'll dive into Sumerian tablets of destiny, Greek divine arsenals, and other mythological weapons to show how removing cultural context leads to some pretty wild alien theories. Plus, we discuss why ancient peoples were perfectly capable of creating compelling stories without extraterrestrial intervention.Get new episodes early and support the show on Patreon and Nebula!Subscribe to It's Probably (not) Aliens for weekly episodes about cool ancient history!

Chariots of Liar: The Truth About Ancient 'Spaceships'

Chariots of Liar: The Truth About Ancient 'Spaceships'

From fiery chariots in the Bible to flying turtles in Native American mythology, ancient stories are full of fantastic flying vehicles and creatures. But while Ancient Aliens insists these are proof of extraterrestrial technology, we dive into the real cultural and religious significance behind these myths. Join us as we explore how ancient astronaut theorists strip away the rich symbolic meaning of sacred stories to push their alien agenda, and learn why a flying turtle teaching humility makes way more sense than an alien spaceship in disguise.Get new episodes early and support the show on Patreon and Nebula!Subscribe to It's Probably (not) Aliens for weekly episodes about cool ancient history!

Beer, Pizza, and Big Rocks: How Ancient Buildings Were Actually Made

From the Great Pyramids to Baalbek, ancient astronaut theorists claim that mysterious acoustic levitation technology was used to move massive stones. But what happens when you actually look at the physics of sound? Join us as we explore the real engineering achievements of ancient civilizations, debunk the myths around acoustic levitation, and discover why using sound waves to move massive rocks would literally liquidize human organs. Plus, we'll dive into the actual historical evidence of how these magnificent structures were built - spoiler alert: it involved a lot of beer.Get new episodes early and support the show on Patreon and Nebula!Subscribe to It's Probably (not) Aliens for weekly episodes about cool ancient history!
