At the beginning of the twentieth century, social scientists predicted that belief in God would decrease by the end of the century because of the secularization of society, but nothing could be further from the truth. Recent polls show that 96% of Americans believe in God. Despite Nietzche's claim that God is dead, He has never been more alive for millions of believers who stand steadfast in their convictions. Why is this? Why are people turning to religion in greater numbers than ever before? Why do people believe in God at all? Shermer also addresses his critics, both believers and atheists, on why belief or disbelief in God is not a question of evidence but of faith. Yet having been a believer and studied the history of science, Shermer is open-minded and inclusive throughout the book. He is most interested in knowing how and why, not in showing right or wrong.
