what if "he" had a messiah complex?
What if we postulate that the Creator of All is also mentally unbalanced, you mean?
I dunno.
I doubt there's much we could do about it.
Why does there have to be an intelligent creator behind it all?

What if it just is?
What if Semi-Sentient Monkeys are the inevitable result of really thick scum growing on a wet rock in space, existing only because of the Time allowed by Mom's Luck as a warm, wet planet?
NOTE: I don't believe I have expressed the belief that (as you couch it) there "does"
have to be an intelligent creator behind it all.
I happen to believe it, but I don't see any reason why you cannot go, instead, with your pond scum theory.
For my part, I think life DID evolve from the primordial ooze. Then I ask myself "o.k. And where did all that primordial ooze stuff come from?"
And then I cogitate and read and so forth. And I come to decide that maybe it did all come from that original big bang thingamajig. But then, inevitably, I ask myself, "o.k.; and where did the original big bang micro-atom come from?"
THEN it starts to get complicated. For, I cogitate some more and decide that I accept as true the premise that nothing comes from nothing. For every "thing" that exists there has to be some something else from which it is derived. Some wise men once said it along these lines: "nothing can exist prior to itself."
It's that whole causation thing.
And yet, if God created the original micro atom from which all matter and energy and time and space eventually emerged, then who or what "created" God?
I dunno. Super God, maybe? Ah, but that just leads to a chain of causation. Super God is the Son of Super Duper God? And Super Duper God is the offspring of Super Super Duper God? Etc. Not an elegant or satisfactory solution.
And, naturally, having cogitated a bit more, I think: If God can exist prior to Himself, then maybe it is time/space/matter/energy that can spring into existence without any prior causation?
I wasn't there at the time, so far as I can recall, so I really can't say.
But it goes beyond just the unanswerable mystery.
For you see -- I perceive a pattern in the universe. These "rules." Laws. Science. Symmetries. Can it really be the case that some random sparking into existence of everything from essentially nothing comes with patterns and laws that we can discern and quantify! I think that's amazing and --
it leads me to believe that it didn't JUST "happen." It was a product of some larger design. It constitutes (to me) a trace hint of the notion that it is
not "random." It was the product of a deliberate CREATION.
Of course, as I say, I wasn't there at the time. So I really cannot say for sure.
