By denying the existance of a god you remove the agnostic. There is a difference between saying that there is no proof and that it is impossible to know and making an afirmation that they do not exist.<quoted text>
Agnostic can be atheist or theist, there are several theist agnostics on here who do not make the dishonest claim that their beliefs are fact. I believe in no gods, and any assertions to a god existing cannot be made without evidence to back them up, thus ... agnostic atheist. I deny the presented gods as they lack evidence, but do not state anything is outright impossible.
I provided the definition I don't know what more I can do if you are too dense to understand it.
Likewise if a person believes in a god then they are not agnostic.
