The op brings up a pretty interesting idea. I could totally see grey aliens being an evolved form of humans that have moved to below the surface.
However I could just as easily see how grey aliens could be humans who moved to outer space and evolved as such because of their environment. For the
purposes of the thread I will entertain the OP's theory though.
My biggest gripe with the theory is that currently, humans are spread out all over the world. We dig, mine, and do all sorts of things underground yet
we haven't even heard a peep about there being any intelligent life underground. Where are these people hiding. If their civilization is so ancient
then they should have a huge populous. There is only so many places underground you could keep this populous before inevitable contact with the
surface would happen. Also since this civilization is a bunch of a humans, one can easily deduce that they like to partake in sex recreationally so
their population would grow much faster than any other species' population would.
Taking this into account I can see how the discussion has shifted somewhat to the civilization being underwater. If this is the case, why haven't we
run into it with our countless submarines or doing sonar of the ocean floor? Sure the world is 70%, but we also have quite a few ships exploring these
seas and I find it highly unlikely that we wouldn't have run into at least a glimmer of a civilization on the ocean floor. Especially since it would
have made the most logistical sense to uproot a civilization and go underwater nearby where they were above ground. This means that this supposed
civilization should be nearby our coastlines.
Of course they could have also gone to such a place as the Mariana Trench or a cave system underwater, but this seems like it would be a little
excessive if they are just trying to escape their doom. They should have no reason to be hiding from the surviving populations on the surface and even
if they were hiding its not like the surface dwellers would have the technology to detect them even if they were near the coastline.
One more thought for both the underground theory and the ocean floor theory, Why didn't this civilization come back to the surface once the threat
ended? I'm sure that no matter how well this civilization fit into their new environment that living on the surface would be far easier to do.
