IF anyone thinks that someone is obliged to produce scientific proof of God's existence for him or anyone else, he overestimates human capacities. No-one has ever suggested that such proof was available, and I don't know why anyone would look for such a thing in such a place. All the arguments about the existence or non-existence of God are very old, and none of them has ever persuaded anyone who didn't want to be convinced in the first place. What I'm interested in is the motives people have for belief - and unbelief.
