Well, doesn't that you have to allow God to create rather than evolve things? He doesn't need to time travel, as He already is outside and inside ALL TIME. There is one God, yet He is infinite and Triune. It is His nature that prevents multiple universes, if you dont count Heaven and Hell as separate universes.
