From the Big Bang, not sure what was before. God does not exist and was not involved.
Not the Big Bang, but some other physical event. God does not exist and was not involved.
God created the Universe without a Big Bang. Earth was especially created.
God created the Universe with a Big Bang and then the universe evolved.
Some other mechanism created the Universe, without God...
God created the Universe in some other fashion...
Then God's actions are not his own, he's just a machine, and saying "God created the universe" is nonsensical, since involuntary acts are devoid of meaning, and the only questions remaining are those of mechanics. Thus to claim that a sentient God does things without any control over them is no different than to claim that the things happen of their own accord, but with the added complexity of "why the hell is this God guy sentient but incapable of action, and who wrote that program, anyway?"
A perfect omniscient and omnipotent god can create a perfectly deterministic universe. She can't create anything else but, if He expects to have knowledge of what Her creation does. From our viewpoint as the Created Things That Think, our only knowledge, from this non-deterministic universe we inhabit, is that any postulated God cannot possess foreknowledge of events in this universe, hence It cannot be omniscient. And if She has a volume of deliberate ignorance in her space, as is required for the known non-deterministic universe She is postulated to have created, then, by definition, she not omniscient at all.
Working with absolute terms is so much fun. The religious types are so proud of themselves when the come up with these absolute ideas and so angry when your local wiseass points out the inconsistencies in adding them together.
