Sure, including time travel and teleportation ("beam us up, Scotty"), but so far we've found no evidence of such activities in pre-historic times.

That's pretty insulting.

Sorry, I should have said: we've found no scientifically confirmed evidence of such activities in pre-historic times.

Of course, I never watch those "ancient aliens" TV shows, maybe something did happen and I never realized it? ;-)

Ancient aliens?

Teleportation?:
