“Hostile to scientific discovery...so prove God does not exist, dummy.”
The theory that God exists adds complexity to the general model of the universe without providing a better explanation of how the universe works. It thus fails by Occam’s razor.
It is thus up to proponents of the existence of God to provide evidence of such. You could, for instance, explain how God came to exist, what God is made of, how God “thinks”, how God interacts with the universe, etc., and provide evidence to back it up.
So far I’ve not even seen a serious attempt to scientifically explain God, let alone a successful one.
If you are referring to the Judeo-Christian God, then science will never be able to prove that he exists. This is confirmed by numerous passages in the Bible which clearly state that God is unobservable and unseen.
A true believer doesn't need the earthly construct of science to "prove" that God exists. Such a person believes in God simply based on faith alone. A believer who does insist on basing his faith on something tangible is going to be very disappointed.
