Atheism
is classified as another religion all over the place. Google it. The reason it is not classified so universally, is that there are atheists who don't seem to know the definition of
religion, who want to classify atheism differently.

I know that to be true but can anyone explain to me
why atheism is classified as religion? I know that theoreticly its belief in absence of god but that would make every person religious and that makes this term pretty useless
