The Argument Over God's Existence.

 Their problem is they have no scientific answer. So they dismiss God's existence.

Reframe the question. Ask can you prove there is no God... scientifically? There is no scientific answer because God and religious belief are outside the parameters of science. Science only deals with natural phenomena; what it sense and measure. God is above nature and therefore supernatural. Which science denies but cannot prove doesn't exist. Christians do not try to prove God's existence scientifically but thru personal revelation and faith. If God has revealed himself to you - made you personally aware of his existence - then no scientific proof is needed. The correct secular answer to God (imho) is to be agnostic and admitting to being unable to determine His existence.
