Hm. Religious fanatics won't understand that, Rule, they will just say "There is a beginning, but only God knows about it." Anyway, time requires space, and in a 0 dimensional universe (pre-big bang), there was no space, and so there was no time. There was no beginning, there was just was.
Sure, but then they have no answer to God's beginning. Time doesn't require space; it just doesn't make sense to refer to the timing of an event alone. Besides, pre-big bang we could say there was space and time in another universe. Likewise, pre-big bang in that universe, space and time in another universe. And we could keep going like this forever.
However, if we understand that time is a property of the universe that we perceive, and that God is an entity distinct from the universe (hence why we say God is "eternal"), the notion of a "beginning" for God becomes meaningless.
Well, I think the notion of an ultimate beginning is meaningless anyways -- without having to make special exceptions and defying reason.
