You are putting words in my mouth, as I have not made this claim. Your logic is flawed here.
A "belief" is a position held indicating that the position is not yet verified as being accurate.
This is completely arbitrary. 'Verified', to who? The belief may or my not be 'verified', to the person holding the belief. The word 'belief', does not indicate whether the person considers it 'verified'.
A "fact" must be verified as being true. It doesn't mean that it is an absolute certainty, but it is verifiable.
Arbitrary again. 'Verified', to who, and in what manner, etc.
If I say "I believe that God exists", it means that I trust that God exists even though it cannot presently be verified as being accurate.
There is no 'verified' except in a subjective manner. Again, 'verified', to who, ...
If I say "I know that God exists" I would be using the word "know" incorrectly, as I have no way of verifying whether or not God exists.
This is subjective. Again, whether you personally do, or do not have verification for something, does not affect the manner in which the words are used.
If I say "I believe that intelligent alien life exists", that belief is not verifiable (yet), but it can still be based on some kind of knowledge (probability based on the existence of billions of earth like planets in distant galaxies, vastness of space, etc.).
So?...
I did not say that beliefs can be disputed. Beliefs are positions. Claims in beliefs, like the existence of God, can be disputed, but not whether or not someone actually holds a belief.
...
Beliefs are positions held as to whether something is the case. Those positions can be based on various facts that lead you to believe something is the case. And, obviously, whether or not a belief is held by an individual can be factual. If Tim believes that God exists, it can be accurately said that it is a fact that Tim believes in God. I can say that "I know that Tim believes in God" because I can verify that Tim believes in God.
Yeah...therefore? The belief does not indicate whether the position is a 'fact', or a 'truth', or in what manner that belief was arrived at.
