"When a Russian cosmonaut returned from space and reported that he had not found God, C. S. Lewis responded that this was like Hamlet going into the attic of his castle looking for Shakespeare. If there is a God, he wouldn't be another object in the universe that could be put in a lab and analyzed with empirical methods. He would relate to us the way a playwright relates to the characters in his play. We (characters) might be able to know quite a lot about the playwright, but only to the degree the author chooses to put information about himself in the play. Therefore, in no case could we "prove" God's existence as if he were an object wholly within our universe like oxygen and hydrogen or an island in the Pacific."
