Your whole religion, like all others, is all based upon the assumption that God exists in the first place.
Forget the Quran, forget Allah's teachings, forget anything else that has been built on top of your religion. Let's go right back to the basics. Can you give any compelling evidence that God exists? No.
We are not atheists because we do not believe in the Christian God; we are atheists because we do not believe in any God. And we see no reason to believe otherwise.
Can you bring us any actual evidence to support your beliefs? That's all we'd be interested in before we even consider converting, to be honest.
