So does God exist? Suppose you, a humble mortal, find yourself inadequate to answer that, what do you do? You go to some of the great minds of our times.
Newton, of course, believed in God. So did Einstein, though his God may have little resemblance to the figure in the Old Testament. Very well, what's good enough for them is good enough for you, you say.
(Pascal had a good argument for believing: there may or may not be a God, you may or may not believe in Him, but you can only lose if there is a God and you don't believe in Him.)
Then Richard Dawkins comes along and not only argues persuasively that there's no God, but writes a book called "The God Delusion" to explain why not. (Watch him explain it to a mock-sceptical Stephen Colbert here.)
Then the ghost of Paul Erdős comes along and says, "Well, I don't know about God, but what about the Supreme Fascist, eh? Someone's out to get me, hiding my glasses and stealing my passport."
