Are Aliens Actually Humans From the Future?

What if some alleged alien encounters aren't actually encounters with extraterrestrials? What if they're encounters with us? In this episode of Probably Nothing, we're looking at the bizarre story surrounding the alleged P-X, P-47 and P-52 beings — creatures claimed to be humans from tens of thousands of years in the future. The story takes us through Dan Burisch and J-Rod, Area 51 and S-4, Looking Glass, branching timelines, and photographs said to show future humans. But how much of any of this can actually be verified? We trace the story, separate what can be established from the later claims, look at the strange photographs and their provenance, and ask whether we're looking at our descendants… or an elaborate piece of UFO mythology.
