Expanding on some ideas.
Always a popular theory is that Greys evolved from a creature similar to our dolphin. Theoretically it does make a lot of sense and out of all the ideas floating around about Greys this one is by far the most plausable. The most noticeable thing about Greys is their grey skin (hence the name, Grey Alien) and is very similar to that of a dolphin. Without an actual sample of a Grey’s skin this would impossible to verify, but there is more evidence to support the dolphin idea than just skin colour. The eyes of the Grey are always reported as big and with a black “eye shield” covering the pupil. On Earth, many water-based creatures evolve these to deal with low light levels found in the ocean, which would suggest Greys evolved in a low level light environment. Another factor that suggests Greys come from Dolphin-like creatures is their very large heads. The size and shape of the cranium infer that Greys have an enlarged rear (occipital) and frontal lobe, a feature that is common in dolphins. During many abduction cases, victims often report that they were unable to move when a Grey looked in their direction, but as soon as the Grey looked away they regained physical control. Certain species of dolphin can disable small fish using sonar, and marine biologists have found that these waves can cause significant changes at cellular level. With many years evolution, it is not that unbelievable that Greys have adapted this technique from an existing skill they gained from millions of years of evolution.
The Dolphin started out like all of us in the ocean, then it became a land mammal, then it went back to the ocean. Its a staggering thing to contemplate on the timescale. But whats to say they all went back to the ocean ? perhaps some did, and some remained. the inland offshoot of the species that just as the land animal became a sea animal once again evolved on a separate path to become the greys ?
And of course.

Pure speculation, but whats to say a planet only spawns one sentient species, Perhaps it does so multiple times. Who knows perhaps in 10,000 years or so the sentient Ape descendants will follow the path of their fellow terrestrial sophonts and step aside and let the next species have the space it needs to climb the ladder.
Keeping ourselves as hidden as possible might be our self imposed penance for the damage and extinction we caused in our messy birth as star farers.
None of which negates the mathmatical likelyhood of the ETH, just the reverse, if thats the model here its likely the same elsewhere. a single life friendly biosphere spawning multiple space faring societys over a large timescale.
Its a fascinating universe, nothing has given me personally greater joy than to speculate on what it holds, and to share that speculation with like minded friends.
Thanks again for an enjoyable discussion ppl.
