Why are people here assuming that there is an unwritten rule saying that a scientist must be an atheist? There are many scientists who are theists. You will have a very hard time, however, finding scientists who are young earth creationists, or old earth creationists who deny evolution. There are simply too many facts, too much evidence, pointing to the earth being old and life evolving. It isn't too hard to weave those basic things into any kind of religious or spiritual ideology.
