it's true, Athiests have the only religion that is demonstrably wrong.
However it isn't wise to question your own faith too harshly, because in the end, however much you might insist otherwise, it is not possible to KNOW, in fact it's against the rules to know. You must have FAITH, and knowledge would obviate the need for faith.
So you can't prove it, and you can't know it, so you're fooling yourself if you claim to KNOW.
And so the argument is stupid, you only get farther from comfort (the real reason for religion) the more you try to treat religion to scientific study.
Take comfort in religion. Use it as a crutch. Use it as a reason to be good if you need more than the feeling of doing good. Use it as the guideline it is.
