I don't think I've ever had this much fun with a movie I haven't watched. That video just caps it off.
Yeah, the whole aliens-created-humans thing is kind of shlocky, but it can be done well, c.f. Larry Niven. His setup was much like the Promethean one, but crucially, he has an explanation for why the rest of Earth's fauna has pretty much the same genetic makeup as we do. It still doesn't quite make sense, though.
