If you start from the assumption that God doesn't exist yes. But if you start from the other option it doesn't. The way I see it, it's like saying that the sky doesn't exist. Some people will say "hey, I see clearly that it exist", while a blind person could say that since they do not see it, it must be that it doesn't exist. That I believe is the fundamental difference between an atheist and an agnostic. I've found that pure atheists often have some beef with the +Ni/-Ne element(for some reason, either because it is not valued or in a bad position such as PoLR, ignoring or linked demonstrative, and/or because they experienced some sort of trauma that made them not consider the existance of god a possibility).
