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 find out that not only were there tools (thousands of them, actually), but that moving big rocks is mostly just a matter of having enough lube. We also discuss why Ice Age: The Meltdown might be a more historically accurate document than Graham Hancock’s entire bibliography, and why finding a fox carved on a rock doesn't automatically mean Noah parked his boat around the corner.

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 cooler than the sci-fi grift. We discuss the "thick disc" of the galaxy, why scientific pre-prints are a media hacker's best friend, and whether the X-Men actually have a space program.

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 "COLD" scale (Confidence of Life Detection), why this rock might be the most important thing ever drilled, and the agonizing reality that it is currently stuck millions of kilometres away because the Mars Sample Return mission is wildly over budget.

Then, to make sure you don't leave this episode feeling too hopeful, Tristan explains why finding independent microbial life on Mars might actually confirm that the "Great Filter" is ahead of us, and that we are all doomed.
