I think it is logically impossible for a single entity to be simultaneously
omnipotent, omniscient and perfectly moral.
For example, I can know fear. God cannot, because God also knows that
nothing can hurt him. He can be all-knowing or all-powerful, but not both
at once.
There is not much to say about how the big bang model does not contradict
any of my current beliefs. It is a scientific model. It doesn't invoke
any supernatural explanations. What do you want?
