ויהי מבדיל בין מים למים
since you seem to be a bit confused, here's a simple way to figure it out: ask yourself how many gods a person believes in.
- if the answer is zero, they're an atheist.
- if the answer is one or more, they're some sort of theist.
The fault here is that you are asking yourself a question about others.
"ask yourself how many gods a person believes in" --- is not a proper method.
A better way is "ask THEM how many gods THEY believe in."
- if the answer is zero, they're atheist
- if the answer is one or more, they're some sort of theist
- if the answer is I don't know, they're agnostic
This begs the question: How can someone not know if they believe? The answer is simple. When asked the question, the person waffles back and forth and back and forth and eventually settles on "I don't know".
