I believe in the existence of a creator. "What exactly does he mean? In simpler terms: What does belief mean? Why is there such a word in our language? What kind of concept does this concept have in our minds?

In the name of acquiring an idea, I repeat the same sentence like other expressions:
(1) "I guess a creator exists",
(2) "I think that a creator exists",
(3) "I think that a creator exists",
(4) "I know that a creator exists".

If the belief word is really meaningful, the phrase "I believe in the existence of a creator" expresses a different meaning in the above four sentences, and therefore none of the above four sentences should be fully met. If there is no such a different meaning, there is no such thing as faith (at least for us). In this case too, it can be judged that there is no such thing as faith, or even if it had existed in the past in the past, there is no opposition in the minds as a notion.
