Pushed by advances in science modernity poses the question; who do we thank for the evolution of man, his morals and his gods-Nature or God? The answer for Christians continues to be based on their belief in the supernatural Christian narrative from which they declare - thank God for creation (evolution). A second answer, Nature, is postulated by Naturalists and is available as an alternate answer. It is advanced by most evolutionary biologists, neuroscientists, physicists and philosophers, who argue that Darwin's Theory of natural selection is sound science and that Nature's biological evolution of living organisms includes man, his brain and his mental capabilities to conceive of supernatural gods. That is, they thank evolution (Nature) for God. The Christian view of thanking God is extracted from several books by leading Christian authors addressing creation/evolution. The book, Thank Evolution for God, examines the basis for thanking either God or Nature for man's evolution, the conflicts presented by these two differing answers and proposes a path to overcome these conflicts.
