Goedels incompleteness seems to me to disprove such omni, and if you are stuck thinking by our best models of thinking, its annoying exponential. Basically, to think about a universe enough to predict outcomes, you have to simulate it. To figure out which universe leads to a desired outcone, it seems like you would have to simulate most of the ones that do not as well. So if we presuppose the existance of a creator, maybe we are one of the failed universe thought experiments as she tries to make her intended universe?
