If there wasn't a God there could be no Nietzsche or we discussing about Him or him !
Who, afterall, looks after this whole play if it isn't God?? Who makes our plans go wrong (or right) ?? If there was no god ,Science would have proved where man goes after death but it cant because God is there and holding them back to get at that mystery!
here is a link for Nietzsche ::
