Establishing shot... Earth time: 2007
Mr. Deity, Lucy, Larry and Jesse grab their favorite table in the corner of the bar.
They are meeting to brainstorm about how to mess with physics researchers who are on the verge of finding the "God Particle" at CERN labs in Switzerland.
While they wait for the fifth member of their party, (young Ms. Fate, who's arrival is proving rather unpredictable), Jesse asks Mr. Deity: "Sir", "Tell us again why exactly you don't let people know you exist for sure or not?"
"Listen, I have refused to prove that I exist," says Mr. Deity, "...because as I've said before, and will say again: PROOF DENIES FAITH, AND WITHOUT FAITH I AM NOTHING!"
"Yes but... Sir?..." Larry worries out-loud, "As we three sit here looking at you, we have no "faith" per se that you exist, so by your own argument, you don't... I mean, you wouldn't, ...would you?... Sir?"
"Oh shoot!," says Mr Deity, (accidentally spilling his drink in the tortilla chips,) "I hadn't thought of that," and promptly disappears in a puff of irreconcilable logic.
(Thanks to the late great Douglas Adams, commenter Nalene and Mr. D.)
"I hear great rumblings...", mumbled the eccentric oracle "Wingo" upon arriving back from the top of the volcano.
