I'm sorry I haven't responded earlier to clarify what I mean by who God is when considering proof of him...Although I haven't responded primarily because i've been out of town, the question has given me pause as I consider what in fact meant...
So let me say that I would like this thread to consider proof of God according to either of the two definitions:
A. What proof would you require of the existence of a deity whose characteristics included at least omnipotence and omniscience among others?
B. What proof would you require of the existence of any deity whose existence has already been specifically postulated via any specific religious text or creed?
