I think its the other way around, though your idea is some Douglas Adams type stuff. Galactic idiots in space crash land somewhere, fast forward and here we are. I like to think that White people are from the stars and blacks were the indigenous feral animals that were altered to be more "human". Though this isn't anything new. Zechariah Sitchin supposedly translated some cuneiform tabs and a lot of the "Annunaki enslaving humans to mine gold from Earth while Nibiru long-orbits our sun" comes from him.
