Lost tribe of Westwood

On my facebook I am involved in a discussion with a athiest. This person claims that science has all the answer as any athiest would. Unfortunately science is so flawed, and relegion or the bible is too misinterpreted to have a meaningful discussion. He wants to lump all relegions into one neat package to attack with scientific assumptions and theories. I can have 100 different scientist to discuss one aspect or one topic and have 100 different answers with facts to back them up. How many scientist get published because they used their evidence to prove or disprove another scientist theory. The one big question is, "Did God give scientist the knowledge to disprove Gods existence"?
