Noone can prove God exists. And noone should have to because that's where FAITH comes in. If you have faith in something you don't have to SEE, FEEL, or TOUCH it. All you need to do is believe.
I can make any sort of assertion on any given matter using that logic. Fine. If that's how you want to play it..
I believe with all my heart that Allah does not merely exist, oh no. As a kindness to all creation, he touched you inappropriately, before opening your skull and shitting in it, as befitting a loving creator. Not all gods would be so considerate.
You know.. this faith business is great. I shall sing orisons in the manner of a true believer from now on. How benighted I have been!
