Instead of responding to the epistemological questions, you cavile about the definition of epistemology. Your #5 is a repeat of #3. A claim is either true or false. 1. X is true. 2. X is false. 3. I don't know. 4. Man cannot know. CLAIM: God does exist = X. 1. X is true. God exists. 2. X is false. God does not exist. 3. I do not know whether or not God exists. 4. I do not know whether God exists or does not exist, and man cannot know whether or not God exists. It is irrelevant whether you accept or deny an empty claim as proof. You either accept/deny the claim that there is no God or accept/deny the claim that there is a God. Do #3 or #4 claim that God exists? Do #3 or #4 claim that God does not exist? FACT: 1. You do not control what you believe. 2. Whatever somebody claims to believe may not be what they actually believe. 3. You can try as hard as you can to believe that you have 10 billion dollars under your bed, it doesn't mean that you will actually believe it. 4. Any claim of knowledge or belief about anything is a belief. 5. If a belief is anything a person believes/knows, it is impossible for one who believes X is true or X is false to not know whether or not X is true or false. Does God exist? <- This is a yes/no question. Somebody who doesn't know cannot believe that God exists or does not exist.
