Didn't Q talk about the greys? I've been looking at posts and can't seem to find anything about it but I'm sure he talked about it.
OK I thought he did my reason for asking was I watched a movie called project adam and some things in it got me thinking. First thing was in the beginning of the movie it said time travel is real second was the aircraft they were using. My thought on it all was what if "ufo's" are really aircraft from the future and the greys are time travelers. Wikipedia definition of grey is intermediate color between black and white. Wouldn't a time traveler be intermediate between past and future? Just a thought
