For every great scientist who says that God doesn’t exist, there is a great scientist who is a believer, and a great scientist who is neutral – but they tend to make less noise about it. Many religious scientists made crucial contributions to our understanding of the world, and of evolution, and it did not diminish their faith – on the contrary. If you are curious, look up J. C. Maxwell or Georges Lemaître or Francis Collins. The fact of the matter is that God’s existence is not a question that can be decided by science.
