Natural theology is the process of observing nature and engaging science and reason to provide evidence for God's existence by "reasoning to the best explanation". It sets aside the revealed word and engages only with the evidence supplied by science, history, and philosophical reasoning to affirm the existence of God. This book provides signposts to God from solid evidence from physics, chemistry, biology, the social sciences, philosophy, and history. This evidence has forced many scientists, including a number of Nobel laureates in science, who have thought deeply about the ultimate meaning of their work to accept Almighty God.
