The battle rages between materialism and theology. The materialist says your life and the universe are just a happy accident with no meaning or purpose, and it will all end, for you, the day you die. The theologians say, no, you were born with the sin of Adam, deserving Hell. But God sent his son as a blood sacrifice to save you from that fate. And if you believe that story, you will inherit eternal paradise. But if you find yourself unable to believe that story, you will burn in Hell forever.
This book explains why you have been conditioned, almost since birth, to believe only one of those stories or the other. Then it presents overwhelming evidence that both stories are both wrong.
The universe does have meaning; your life has a purpose, Hell does not exist, and your fate has nothing to do with religion.
