Here's a strange rebuttal for you:
To me God is the God of life, not of the cold and hot rocks in the universe.
How can I assert this?
By answering the question, "What is God?"
God replies, "God is love."
Only life forms appreciate "love."
Therefore, I argue that the universe was here first, we came later and our God, being the God of life, is within each of us.

That would only be a rebuttal if I had stated that God's existence is a certainty. I merely stated it as a possibility, to which you have added another possibility! :-)
Of course, I do have faith that God exists. To me, His existence is a certainty. But for purposes of discussion I always maintain God's existence as a possibility in recognition that not everyone shares my faith.
