When you say you believe or do not believe in "God", what exactly is your definition of "God".

[MarvinGardens]

37. It's a good question.

This brings up the question in my mind: Was there a point of origin of the universe, or is the existence of the universe an infinite series of events stretching back in time forever? The cosmologists can't see back before the big bang, but that does not mean there was no existence prior. Infinite series exist in mathematics, so why not even in the physical world? In Western religions, the answer is that God is eternal and has always existed, thus God Himself had no creator. But if we instead ascribe that property to the physical universe, then it can be argued that the universe needs no creator.

Even if the universe is an infinite series in time, it is possible that it has a creator. This may at first seem absurd, but consider that time itself is a part of nature, treated as a fourth space-like dimension in some of Einstein's equations. It is possible that God created a universe that had always existed, forever, from our perspective.

Why is such a fanciful explanation necessary or desirable? For me, it is because I have repeatedly had the following profound revelation while lying in the dark contemplating such things: None of this should exist, yet it does. To me, this is intuitively true. Why then is there existence rather than non-existence? An intelligent creator is the best explanation I can come up with.

But I still have not answered your question. Where did God come from? If indeed He created time and exists independently of it, no answer is needed. He was there B.T. (before time) or outside of it. But because I'm on here answering questions I don't really know the answer to, I'll entertain the possibility that God had a creator, an Ubergod. In that case, perhaps the Ubergod also had a creator, and so on, ad infinitum. In that case, we could have a universe that appears either finite or infinite in time, and in addition have a God who is one in a series of infinite God-creation events.
