If you believe that a loving God created Heaven and Earth in 7 days, and died for you and is coming back to recieve you back unto himself, you need faith. If you believe that some mysterious explosion created all sorts of rocks which collide into each other to create all sorts of living beings, which would go on to evolve from a tree swinger to a NASA scientist and beyond, you need faith. Either way you look at it, your in a religon that requires some sort of faith. To prove or dissprove either sounds like a pretentious and persumptuous idea to me. Why should I listen to a monkey brain over a God spirit. Or perhaps why should one listen to a "non-existant" God spirit over their monkey brain? Sounds to me like this question has no worthy answer.
My brain, logic, and the spirit of God.
