You have a vested interest in maintaining your "self-integrity" with has a requirement of "a God". I do not. I am aware (in line with the observations of countless others) that my experience of "self" is inconsistent and a function of situational factors. Arguments which undermine the interests of a particular self
would certainly be deemed by you
(the believer) to have "no existence" in its
eyes despite the fact that this ironically reinforces the perceptual bias argument per se
Logic based on a premise of naive objective realism is vacuous.
Like all believers in gods, you seek the absolutist cocoon of "certainty" and "meaningfulness of your existence" in the face of the inevitability of change and mental incapacity. You only need to look at the continuous paradigmatic shifts in scientific knowledge about we call "reality" to appreciate the simplistic nature of such wishes about "certainty".
Of course you can always attempt operate the catch-all clause of believers that "all knowledge is in the gift of God", thereby putting up the mental shutters against potentially troublesome thoughts.
