In my universe, a long time ago the humans were just space dust that hadn't even formed into a planet much less developed life, while my race was fighting galactic battles against species who would destroy all civilizations but their own if given half a chance. The Racnoss, the Great Vampires...

And now the humans are one of the Temporal Powers, with time ships of their own. [Narvin used to not like this idea AT ALL. Now...he's rather all right with it. Humans make good allies.]
