Atheism isn't a beleif either, by that reasoning. I don't beleive 'god' exists. I'm suspending my judgement until I have proof otherwise. It isn't faith that leads me to beleive this. It's lack of reason to do so. It doesn't take a conscious effort to not beleive something, whereas beleif in something does. I don't have 'faith' that the yeti isn't real. I have no reason to think that it is. Requires no faith to make that call, on my part.
