I don't know, I wouldn't call atheism a religion.

"Buddism has no gods either and it's still a religion"

Actually it does have some gods ;(

I don't think nihilism has anything to do with God being dead, per se, as existence being bullshit ;(

"It affects your inner most morals and belief of the how the world came to be."

It doesn't effect your morals to say there's no god. There is no atheistic creation story.

"The lack of religion has it's own beliefs IE there is no God and no afterlife."

I don't think atheists believe it so much as they have no evidence to the contrary.
