I doubt many Christians would accept that their self-inspired image of God and Jesus are completely wrong, and that their existance was a random unintended cosmic glitch rather than design.But the point is, like many of us, we think we know what our creatior is but when we actually encounter Him, He tends to not be exactly what we think but does end up being the answer to everything and completes us as Vejur's Creator (a human) did for it.
I also doubt they'd accept that their Creator is unaware and indifferent to their existance, bears no conscious answers or intentions towards them, and that the path to true enlightenment/Heaven is to discard belief in favour of physical proof.
That's pretty much what occurs in ST:TMP.
The machine planet who gave Vejur the vessel that birthed its first moments of consciousness are more its "Creator" than anything that mankind does in the film. They at least did it on purpose, gifting it with the capacity to complete its mission, subsequently resulting in its first thoughts and flicker of consciousness, instead of tripping over it by accident and failing to even recognise it.
