>But basically I believe the gentleman has a fair point - it is not possible, at this point in time on our planet, for any one belief to be the "correct one," since the precepts of any one religion or belief, including aethesim, cannot be proven or disproven. In that sense, they are all basically untenable, and merely "faiths."

I have to disagree with your inclusion of atheism as a religion or a belief. Literally, an atheist is anyone who is not a theist. In otherwords, atheism makes no claims of its own, it simply is skeptical of the claims that theism makes.
