Time—Philip Johnson is not just a Christian but a creationist. Do you mean, “if there are smart creationists out there...”? I don’t really pay much attention to the religious beliefs of the smartest mathematicians and scientists and I’m not especially keen on looking into it now, but I would be surprised if all top scientists without exception were atheists. This page seems to suggest that many of the best scientists are something other than atheist, many of those Christian.
