In order to continue on a sensible footing, let's outline a 'sketch' of God that we can all relate to in general terms. This God created the universe, His son, Jesus, was born in Bethlehem, the mother of Jesus was Mary. God and Jesus both performed miracles. Jesus died on the cross. God is in heaven.

I won't add more to this definition because the more I define God the more chance there is that we will disagree on some minor point or other. The idea is to simply agree on a very broad definition in order that you all be of the same mind when you talk about 'God', otherwise you will be on the roundabout again.
