About 120 million of us place the big bang 2,500 years after the Babylonians and Sumerians learned to brew beer. If our polls are to be trusted, nearly 230 million Americans believe that a book showing neither unity of style nor internal consistency was authored by an omniscient, omnipotent and omnipresent deity.

Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it.
