So what you're saying is three million years ago, our ancestor met their ancestor. Their ancestor was smarter so either manipulated or ripped off our ancestor, or our ancestor was just scared of this other being...

Our ancestor then promptly beat the other being to death and hunted them into extinction, sort of like what we did to the neanderthals...

So a hundred years ago someone found this thing in a dig as they do and thought, 'hey with this really big brain, I wonder how smart this critter is ?.'

If this critter was alive we'd have found him sooner.
So someone grows some blood cells from the critter in a dish somewhere, and after several decades a critter crashes some craft made from the ideas of a guy guy called tesla...

Wow, that's a hell of a story... Makes you kind of wonder what else they're doing in secret labs all over the place, there's probably a movie script in all this.
