Why Agnostic?

[Purple Rabbit]

Even if some religious groups say their explanation is "the truth", all one is required to do is to believe in it, not state it is absolute knowledge (and those who do state such things are the ones we call "gnostic").

No never. Your re-invention of the word 'gnostic' wipes out the position of all religious faith, because none are gnostic, all are agnostic according to you.

Like you inside the room, no one can know empirically if God exists or not. No one has empirical proof. To take the position of faith further and make positive claim from empirical grounds is unsubstantiated, and beyond logical consideration. I certainly wouldn't consider it/ or I could easily justify dismissing it as any more than a theoretical consideration. Christianity doesn't back up your statement of absolute knowledge anywhere.

Christianity may not base their claim on empirical evidence (the roman catholic clergy surely have tried it though), still many christians claim absolute knowledge of the existence of god. What a diffferent world would it be if relgious believers would acknowledge the fact that (their) god could possibly not exist at all.

The claim of believers of whatever religious flavour is to have other epistemological means than empirical evidence and deductional logic. This claim is an insane attempt to justify their belief that presents itself as just the next offspring from mystical tradition. Nothing new under the sun.
