And when you are done, & specially if you've heard of Type III civilizations (civilizations that are able to harness the power of entire galaxies, we at present are a type 0 civilization - but heading for Type I - planetary - able to harness the power of a single planet, on the Kardashev scale), check out this article re: the possible relationship between our human civilization & a Type III alien civilization.
And a few people are/were discussing Type III civilizations here. The idea of Type III civilizations are interesting because such people (or aliens) would have the ability to create universes & possibly new species of animals - basically the powers attributed to "creator gods" in ancient human mythologies & creation stories.
