Formally, I classify myself as a gnostic atheist, meaning I know there are no gods. Most atheists (from what I read online) appear to be agnostic atheists, people who are without gods but who do not claim to know there are no gods. Some people who fit this description simply call themselves agnostic. But, on formal forums, like reddit’s atheism subreddit, all who are without gods are atheists and agnostic or gnostic is a statement of whether they know or have doubt. Similarly, they allow for agnostic theists, those who believe in god(s) but have some doubt.
To begin our discussion, we have to classify gods.
