Here is the answer to that question. Imagine we were wiped tomorrow. Our space junk would be up up there for thousands of years. So if it hit tomorrow we go back to the stone age thousands of years pass. New monkeys go into space see our old space stuff… there you go.

Think about this. We went to space found past civilizations technology. Brought it down. Now we have super computers. UFOs. You think they want to bring back the mammoth? What about collecting old civilizations dna and bringing them back?

What if all this bs is old civilizations trying to rebuild their lost empires?
