It can be equally said that "the belief that there is no God is a concept envisioned by man"
Do you believe that somewhere amongst the millions of stars there could possibly be a planet with intelligent life? There is absolutely no factual evidence of that, but many people hold that belief, there are large organisations supporting that belief, even fanatics, probably even the odd pedophile. Could this be religion, the belief in something en-masse. There are atheist organisations, atheist preachers (Richard Dawkins maybe) Atheist papers and books(scriptures) Everything is in place to call Atheism a religion.
Many people call themselves Catholic but don't ever attend church or behave in a Christian manner. yet these people are labelled religious.
So yes Atheism in reality is just another religion.
