From my experience with atheists, they seem to be just as avid beleivers that there is no God as a Muslim who believes in Allah, some coming to intellectual absurdities to hold on to their atheism. One atheist I'm talking to right now keeps asserting that there is no meaning in the entire universe - that your "thoughts" are nothing more than the accidental by-produce of the collision of atoms, and so there really is no such thing as "thought," since your brain is merely reacting to outside stimulation by unintelligable, arbitrary forces. I told him, however, that such a position is self-defeating, since if his words were true, his words couldn't possibly be true, since they would contain no meaning. His conclusion would be just as intelligable as the phrase "iojckjkles:" completely void of meaning. We cannot mean to say there is no meaning, since if that were true, we should have never found out there was no meaning. It would be just as if we lived in a universe without light, so that we wouldn't know color to say that there is none.
