Can you produce anything from this "belief system"?<quoted text>
The belief system that's based on the belief that there is no God.
If it's only one belief, it's not a system.
So, what else is part of the system?
Did you just make it up?
What is that belief system called, and do you know of anyone that follows it?
Besides that, we've told you before, again and again, basic atheism is the lack of belief in gods.
No valid definition of atheism invokes the name of any specific deity.
