I still don't buy that the *only* aliens that exist out there will be more intelligent and more advanced than us.
Our existence was a very awesome set of near-impossible coincidences that aligned perfectly. Wht's the chances of life evolving on other worlds at a rate faster than us? It's possible, but I personally think we'd be one of the higher rated species in at least this galaxy.
We need more stories about us being the aliens, as opposed to encountering these super-almighty war-going beasts that constantly plague sci-fi.
