On this episode of Skeptico, a show about what's going on in space now.

How big? It's what we call a global killer. Nothing would survive, not even bacteria.

And it's seen straight out of the movie Armageddon. Real-life NASA scientists are going to rame a spacecraft into one massive asteroid.

And 78,000 years ago.

Again, for this very reason, they understood this appeared to be already glass and to have come from space.

So a lot of the NASA guys were arguing this had to be lunar material.

That theory collapsed when we retrieved lunar materials and realized it did not mesh.

But their argument was very sound.

One of the guys actually said, well, look, what about if it came from interplanetary space

or somewhere further out?

Well, that's a problem.

No one can tell that seriously because what's the chances that it ends up in a geocentric orbit?

That first clip was from the Today Show.

And the second one was from today's guest, Bruce Fenton, who you've heard on this show before.

And I can pretty much guarantee you you will hear from him

again. He's doing, I think, just about the most important scientific research into ET UFO,

the phenomenon, if you will, then, well, really just about anyone else I can think of. And I think the reason for that

comes through in this interview. Stick around. It's a good one. Welcome to Skeptico, where we

explore controversial science and spirituality with leading researchers, thinkers, and their critics.

Today, we welcome back Bruce Fenton to Skeptico. Bruce is the author of several books.

I pulled up one of them you can find on Amazon,

Exogenesis Hybrid Humans, A Scientific History of Extraterrestrial, what's the rest of that?
