Ad-***: The ad does deny the existence of Allah. 'God' in this statement covers all gods, like Yahweh, Jehovah, Thor, Zeus, Wotan, Jesus, the Holy Ghost and even my personal favourite - the Flying Spaghetti Monster. The ads would have been too long if we'd had to name each one that doesn't exist. Also, I can't see why Christians should be incensed at all. The ad says god 'probably' doesn't exist. Whereas really, god almost certainly doesn't exist.
