No, there are things for which there can never be proof, because they lie outside the realm of proof

Everyone says that. Until proven otherwise. Time, Creativity, Necessity and even Boredom prove that idea wrong time and time again. Just because you can't comprehend it now doesn't make it incomprehensible. That's like someone in the 3rd century saying we'll never prove that the moon isn't being chased by wolves across the night sky.

It's why no-one can realistically guess at the working of a post-singularity world.

Electricity did not spontaneously invent itself upon Benjamin Franklin's discovery.

No, it did not. But it made the people running around saying "There are some forces that man just cannot harness or understand!" look a bit silly, didn't it?

You have a lot of nice, poetic notions, but ultimately it's just talking while not actually saying anything. The steadfast approach of "No, you can't prove everything and what you think you know is wrong" while throwing around pseudo-scientific spin-terms like gnosis, awakening, being reborn, enlightenment is basically anti-intellectual /r/iamverysmart flat-earther logic.

The truth has always been there, even in a total absence of recognition.

And you're assuming to know that truth with no evidence, like a man who spent his whole life in darkness claiming there's no such thing as light. Or claiming that fairies exist because no-one has proven they don't. Or making some arbitrary claim that some magical, unobservable fairy dust makes everything sentient, and it really is sentient but you can't prove it so we just have to take your word for it, promise, just don't ever try to prove it because you can't, you're better off just blindly believing and obeying.
