well, mote.of.soul, I'd say that I don't know. the universe may be eternal, in an endless cycle from creation to death and reincarnation as the Hindus believe. It may be eternal in that e.g. black holes recycle energy or move it from one corner of a multiverse to the other and thus it never dies, and never is created.
Granted, if it has a clear cut beginning, such as a big bang, this makes a creator more likely. However, I would point out that no scripture I am aware of ever states that God created "something from nothing", as such his power only seems as omnipotent in comparison to ours.
