[@Double] What I was saying is that it's possible that at one point someone talented enough reverse-engineered a stray spaceship and flew away from Earth. That could be a single person escaping Earth for whatever reason. Humans don't need to colonize space, in fact I was thinking of changing the trade planet into one with many races in it.

Also I guess I'll remove the half-Saiyan part.

(I'll play as a cute anime girl if you're not still not okay with this. Are there already enough of them?)

That stray ship had to have come from somewhere, but I can't think of any.... wait, yes I can. Kami's ship. Soneone could have discovered Kami's old ship in Yunzabit Heights, but whether they could just claim it without him knowing is another matter entirely.
