But an omnipotent god? We've seen them die, kill each other, grown complacent and bored, and in need of help from a mere human to find their way out of a civil war. Personally I don't consider them gods, just as we aren't gods even though an ant might think otherwise.
Or, to quote Quinn:
You mustn't think of us as omnipotent, no matter what The Continuum would like you to believe. You and your ship seem incredibly powerful to life-forms without your technical expertise. It's no different with us. We may appear omnipotent to you, but believe me, we're not.
