You are confusing atheism with agnosticism...

I certainly am not. Atheism is a lack of belief in deities.
Agnosticism addresses knowledge, not belief. There are agnostic
theists and there are agnostic atheists. I lean towards the latter,
believing the question is potentially knowable, although it many not
be.

Then, what is the difference between atheism and nontheism?

The prefix? I've seen the term used in philosophical discussions
occasionally, but it's really not in common use, and I don't know
anybody who uses "nontheist" as a personal label.
