where he goes, this rock speaks to us from across the generations, and if confirmed, will undoubtedly revolutionize our understanding of the universe around us. Now, the movie clips that clip to make it seem like Ellie, the fictitious character, discovered SETI, extraterrestrial technology, not a microbe. But In the public's mind, that actual scientific discovery was never falsified.

It was certainly never confirmed. No one has ever come back to say that was correct and that we did find microbial evidence of microbial life on Mars. Now, how did that meteorite get there? Well, some asteroids hit Mars. the Moon, that's why it has craters on it.

It hits the Earth, that's why we have Meteor Crater Arizona, Winslow Arizona, Yucatan, Chicxulub, where the dinosaurs' doom was sealed by the giant impactor 66 million years ago. Those impacts occur on every planet every moon in our solar system.

So some asteroid hit the surface of Mars probably millions of years ago, ejected material, low gravity on Mars, low atmosphere, and that material has been orbiting around and eventually made its way and hit the Earth. Okay, so matter from Mars landed on the Earth. Does that make sense?

That's how I gave you – I have a lunar meteorite that I'm giving to you, again, as a token of my appreciation for all you do. That came the same way. Something hit the moon, blasted off some lunar – it's called breccia. It's the crust of the moon. Eventually made its way, landed in northwest Africa, and I bought a slice of it from a I got a dealer. I got a meteorite dealer.

And I got that for you, OK? So what's the lesson? Material gets exchanged from planet to planet. Now, I ask the following question. If that happened on Mars to the Earth, the Moon to the Earth, so too has material from the Earth been ejected since life emerged 3.7 billion years ago, there's literally millions of tons of Earth that's floating around in space. Some of that will have landed on Mars.

So someday we'll get there. We'll find some piece of it. Now, could some of it have a tardigrade on it? Could some of it have a protozoan on it? Obviously it could.
