Did gods create mankind, or did mankind create gods? Why, when and how did mankind begin to worship gods? Religious scriptures the world over claim that one or the other god made man, but science has not yet identified any supernatural power that created and governed human beings. Was it man who came up with the idea of gods to help him cope with his own fears? Could it be that ancient people attributed natural phenomena-unfathomable and frightening to them-to the working of invisible gods? What kind of sufferings or bewilderments made people bow before unseen powers or gods as we call them? When were these gods created? Who invented morals and methods of worship? Who wrote the ancient scriptures such as the Bible and the Vedas? Most crucially, have gods and the scriptures shaped our responses to the world around us? The Evolution of Gods seeks to answer these questions, and explains scientifically how, when and why religions and gods came into being. Ajay Kansal marshals anthropological and historical facts about the development of religions in a simple and straightforward manner to assert that it was mankind that created gods, and not the other way around. Dr Ajay Kansal is a professor and consultant in clinical pathology. It was during his medical practice that he encountered human suffering in a big way that made him question the concept of gods and drove him to write this book. The medical knowledge of the author has added much value to the book that describes human evolution and their struggle with epidemic diseases.
