Come out of the box. You don't "believe". You either know or do not know.

believe you know. The more evidence you have, the more confidence you have that what you "know" matches reality. The less evidence you have, the more you have to rely on belief and the less (real) confidence you have in what you "know".
You pretend to be confident that you "know" but you don't present any evidence. Your belief is empty.
