Seems there still is a belief.
It seems you're not separating out the difference between strong and weak atheism, and that's pretty significant.
Strong atheism: the belief that there is no god.
Weak atheism: a lack of belief in a god.
Edited to add--weak atheism is the more typical kind, and that's what I self-identified as for years.
Personally, though, it seems to me that all the evidence points to gods being human-imagined constructs, and therefore I not only lack belief in a god, I believe that there is no god, based on currently available evidence.
But it's not the same meaning of "believe" as religious people use. The point that used to puzzle me about the definition of "strong atheist" and why I didn't used to self-identify as one is this: I thought it meant not only did you believe there was no god, you planned to maintain that belief
regardless how much evidence might theoretically come forth in the future for a god. That would of course be silly and put strong atheism on a par with religion, where keeping the faith is more important than evidence.
But apparently, it doesn't mean that, and I learned that in fact the "belief" is understood to be only conditional, based on current evidence. That's when I switched to self-identifying as a strong atheist.
