I often get confused about who the real Christian God is. Sometimes it appears to be Yahweh, other times Jesus. It seems to me, that Christianity is actually polytheistic.
Regardless, over time, our increasing knowledge of the cosmos has invalidated much of the 'information' about the cosmos found in the Bible. This supports your statement, berrygerry, that the Christian God is stupid. Of course, knowing what we do know now, many of us have concluded that 'God' is, as erbie and galaxie have said, a construct of the ancient Middle Eastern desert dwellers' imaginations.
Whatever the reasons Constantine and his merry band of men had for compiling The Bible, today, it is definitely a tool designed to validate the Christian religious industry and its right to manipulate and control people. I think Yahweh was the ancient Israelites attempt at validating killing and warring with other tribes who did not believe as they did, thus, starting the 'our God is better than your god' and 'our religion is better than your religion' beliefs that carry on into present day. Anything can be validated and justified if the right god is on your side.
