To the people just answering "Atheist" to this question. You're stupid Atheism is not a religion.
"Calling Atheism a religion is like calling bald a hair color".
That is why I have no religion, I am my own god. I am proud to be an Atheist.
I am not a Religion. Do you mean the practice and believe system ?? I do not do religion. NONE of it. I hate religion as all are artificial which creates hate and war.
