" The Evolution of Gods utilizes modern science to explain why, when and how religions and gods became the desirable explanations of inexplicable events. What kind of human sufferings necessitated people to bow down before unseen powers called gods? How did mysteries of nature give birth to divine powers? Who invented morals, methods of worship and the ancient scriptures? In order to answer these and other related questions, I have compiled a brief history of human religious activities from several reference books, and these are listed in the bibliography. "
