Let's say this claim is true.The Bible is evidence of Gods exists.
If it is?
What SORT of god does the bible describe?
The bible's god is a rapist, a murderer of innocent babies, a destroyer of entire nations, a drowner of innocent kittens and puppies too!
The bible's god is an egomaniac who murders anyone at the slightest whim, who demands constant ego-stroking, and is jealous of the least little thing-- is even jealous of love humans express for each other!
More: the bible's god uses TORTURE to get and keep followers-- and not just ANY torture, but INFINITE TORTURE.
So, to sum up?
The god the bible "proves" is an sadistic, egocentric, maniacal terrorist of the most common kind.
