Yeah what he said.
Atheism can be like a religion, in that people can get quite fired up about it, but there is no one unifying organization of atheists, they simply don't believe in god(s).
It can be said that science is a religion, since it is an organized set of beliefs and, by its nature, seeks to find the answers of the universe like where did we come from, where are we going, etc etc. But that said, there are many Christian, Muslim, etc etc scientists that do not view science as a religion but as another way of figuring stuff out, and those same scientists are very devout in their (spiritual) religion. It seems to me that science is what you make of it, it can either fit inside (or work with, however you phrase it) your religion, or it can be something entirely of its own that trumps all other religions; it all depends upon what you choose to believe (or what you find to be true, again, however you phrase it).
But that's another thread all its own; I can say that I don't find atheism to be a religion proper, but a general religious conclusion that there is no religion to be had. So it's not a religion in the common usage of the word, but religious beliefs do make up religions. I suppose atheism can be thought of as a religion, even though it's a very grass-roots type religion with many different underlying philosophies that lead to the 'there is no god' conclusion.
Edited for clarification. What I mean is that Athiests don't necessarily agree on anything but the lack of any diety.
