Figures, we atheists finally get a thread of our own and it gets hijacked into some "Pope is only a man", "My god is better than your god" thread.
As far as the original question, I've said it before, you can always tell an atheist by the tail! Sure, we can hide them pretty well, but if you get real close to our buttocks, you will see the lump.
And babysitting your children? Ha! Not unless you want Small Child Stew! A classic favorite of atheists.
As far as belief ---- well, not so simple. The prophecy goes something like this; our "No god" will someday rise up against the vicious and rude christian god and beat him in a 3 round brawl, ending in a split decision for the atheists. Now hopefully we calculated all of our sacred texts because if we are off by one number, it's actually the christian god that wins.
