It should be obvious by now that the "ET" PsyOp was the Hollywood cover story to conceal DOD's own covert advanced technologies. The "greys" were the original NPCs.
I don't know if intelligent ETs exist, but if they do, they would look beautiful and functional, the way humans do. For example, they would not have a head so large that it would snap off, if they bent over. George Lucas understood this, but apparently Spielberg didn't and instead relied on Crowley's cult of Lam nonsense for his movie making.
