What/Who created God?

[fr0d0]

God would interact with any moment in our time in all time. As God is timeless there is no past for him... doesn't he live the whole thing as one moment?

If he knows what he is going to do at any given moment then he cannot do something else, if he does then he did not know what he was going to do.

His action at any given moment in our time would be completely perfect, so he has no need to change his mind, as that would imply an imperfect decision, which would be impossible.

If his mind exists at an "end state" of time then he has a past, this is incompatible with your previous statements.

I agree. He can't have a past.

God's lack of need to change his mind is unrelated to his lack of ability to do so.

God has no unresolved challenges, or he wouldn't be all powerful or all knowing. I think changing your mind is purely a time bound task.
