You're absolutely bang on, there. I couldn't agree more.
I'm still unsure about the purpose of aliens on Earth, but I do know that they exist. I just hope that they are friendly if they do introduce themselves to us in our lifetimes. I remember the late Dr Karla Turner saying that more often than not, the various alien types are in company of the greys, which if true, complicates things further. She was obviously a very intelligent woman, so I won't speak badly of her, but what was said in quotes on her memorial website, it is jaw dropping stuff in one way, but quite confusing in another. I have my own theories from what I have read & what I have seen on documentaries, but I'm not sure either way of what to think. I reckon the greys are either a slave race used by all the different species for their own purposes, or it is the other way round. I sure as hell don't think they are demons, though. Just my opinion, anyway.
