Watch ALIEN and see the part with that huge skeletal looking dude on the chair supposedly looking through that huge telescope. He's dead, huge, and pale, sitting on a chair that he's seemingly stuck on. Search Space Jockey on google and/or yahoo. You'll get a picture matching my description.
A Space Jockey is rumored to be the creatores of the Alien, or the enemy/supplier of the Predator. I don't know which one is fact, but then again all of them aren't fact, for now.
