Personally, I wouldn't go so far to say that Atheism isn't a 'religion'. A religion would be based off of a set of higher beliefs conservatively kept, mainly pertaining to a divine entity, but alternatively can be something material. What makes individuals think otherwise is the fact that it is just one that doesn't promote 'spirituality' and 'faith' in a divine entity. (Science not being a divine entity. It is a matter of study and a philosophy that we can materialistically comprehend.) ... Though, doesn't make you think that if perhaps Atheism can be considered a religion, then couldn't any philosophy for that matter be considered a religion. Therotetically, yes, it could. However, as far as majority comprehension, it just isn't. -Pyronide
