The existence of God has long fascinated the human species. Based on a system of belief and several historical encounters with God, people have built their religions. Whenever something bizarre bothers someone, and that someone takes refuge in divine guidance, hardcore religious preachers give only one absurd answer: "God works in a mysterious way." But has this so called God ever been experienced by any mortal being, or was it all very biological In the book the author takes us to the scientific land of investigation where we shall explore the true biological foundation of God and religious beliefs. In this fascinating journey of neuroscience we shall discover how exactly we humans constructed God and not the other way around.
