5. Alister McGrath
We are continuing our list of atheist scientists who now believe in God with McGrath who is not just a Christian now, he is actually a priest. Before his conversion he was a staunch atheist and science was his only passion, but as he started to grow up, especially in his undergrad years, he realized the importance of religion and started to accept the teachings of Christianity. After accepting religion, he even taught historical theology at Oxford University. He has since become critical of Richard Dawkins and has even debated him several times.
