I mean if you sit back and actually think about it, surely you don't really believe in god. Sit back now, think about god. Think. Think a little more about him. Now tell me, do you actually think he is there? Honestly.
I know nothing of the Koran, but I have been told that the promise to martyrs of 72 virgins is based on a mistranslation, whereby the Arabic word rendered as "virgins" actually means "figs". Imagine what a let-down that will be!
Haven't read through the posts, but regards the question: It's one of the crassest, most obtuse, patronising ones I've ever read. Did you honestly believe, flob, that through thousands of years, no-one has ever done this? Did you think that you had had a unique revelation? Thousands of books, millions of discussions and billions of people have dwelt on the subject of theology, yet no-one ever thought to 'actually think about it'.
