Those that feel that their Faith is disturbed and diminshed by a mere Fact couldn't have had a very strong Faith to begin with.
i remember reading the reaction of the scientist who figured out the three dimensional shape of a DNA strand. It was basicly a well organized blob. He said it was hard to not imagine the hand of God nudging things along.
They care more about what others think than their faith in God.
They need "proof" of God to show others so they won't feel so alone and unpopular.
