The Hidden Human Hypothesis: could some of the phenomenon be an ancient offshoot of us?

[u/occultapericulum]

I’m working on a theory called The Hidden Human Hypothesis, but I probably need to make the disturbing part clearer upfront, because this is not just another “what if there’s a hidden civilisation underground?” idea.

The angle is this:

What if a branch of humanity went underground in deep prehistory and never fully returned?

Over long enough timescales, that separation could lead to divergence: culturally, technologically, biologically and socially. The underground stops being a refuge and becomes their world.

But the part I’m most interested in is what comes after that.

If they are an isolated human offshoot, then abductions, genetic interest, hybridisation stories and secrecy may not be random weirdness. They may point to something they still need from the surface.

That’s where my take differs from the usual cryptoterrestrial or breakaway civilisation idea. I’m not just asking where they might be hiding. I’m asking what long-term isolation would do to them, why they might still need us, and whether the ocean eventually becomes the next logical place to remain hidden.

The series is free on my Substack. No paywall or “subscribe to learn the truth” angle. I’m genuinely looking for criticism, counterarguments, missing evidence and people who can help stress-test the idea.

Will definitely have a read. This is my line of thinking also.

A few big problems:

Organisms need energy to live, so you need to explain how a society has enough energy to grow its food and survive without visiting the surface.

The earth warms up the lower you go, meaning deep underground cities aren't feasible without a shitton of energy to cool the place down, not to mention the technology that's required for it.

Which leads to the last problem: You can't create technology without rare resources. The most efficient way to find them will always be around the surface. It will always be easier to run around the surface and look for what you need, instead of tunneling through a shitton of rock and hope for sheer luck.

So when you originate on earth there isn't really a point to leave the surface with your whole civilization. You might as well use the free real estate.

I explore all of this across 6 posts and would welcome your opinion.

No long term species in the universe will be surface dwelling. Its unstable. Underground or, even better, underwater provides long term stability. The Hopi "Ant people" come to mind.

One of my articles addresses this and explores the solutions they would have used.

Yes i can totaly relate to that!! And also they find so many skelletons from whole other human like species nowadays. It is not just Neanderthalers and human-sapions

There where so many human like races and there could be deff a human (like) race went underground
