If you're curious about that, look into the theory that the Moon is a spaceship, with a satellite civilization that was supposed to help humanity evolve naturally behind the scenes but, instead, came down and taught us forbidden knowledge and had off spring with our women to create the nephilim. (The book of Enoch, referred to as the watchers)

In that theory, this civilization was run by an AI (which you pretty much have to have in order to traverse through outer space) which is rumored to be an engram of Satan. If nothing else, it's at least some interesting stuff.
