There are scientists who are atheists and there are scientists who are Christians. Is there a difference? As far as talents, intelligence, and qualifications go, there is no difference in favor of either side. At the beginning of the modern scientific era, scientists who were theists far outnumbered atheists and agnostics. That balance has changed in more recent times in favor of the unbelievers. But there are still many highly qualified scientists who are firm believers in God.
