No scientific proof of God's existence is possible, imo, since Western science is founded on observation only of things that can be mathematically quantified and/or logically categorized. God, being prior to all existing material creation, simply cannot be observed. His existence, or non-existence, is simply not a scientific question at all. When people like Dawkins hypothesize about God and revealed religious truth, they are WAY out of their field of expertise. However, before you write me off as a fundie religious nut, let me say that when religious people bring their religious assumptions to the science debate, they also are operating well out of their own field of expertise. This debate has generated much heat and friction, but no light whatsoever, and I have read countless Crevo threads and the posted links.
I remain a believer in a Creator God, but I would be absolutely astounded to learn of any tangible scientific evidence for His existence. Just as psychologists have studied the human mind and neurologists the human brain and nervous system without discovering the human soul that dwells within us all. Why? Because the purely spiritual is invisible to the scientific eye.
You do believe Christianity is based on evidence?
