from what i read and watched on tv and movies ... the SMALL GRAYS are not actual life beings ... they are AI (ARTIFICIAL INTELLIGENCE or robots) the Large Grays are the real aliens and they come in different forms so far 57 different kinds of them

Apparently the lil 3-4 footers are "workers" the larger 5-7 footers tell em what to do...
They all look like Praying Mantises...
Must suck not having a cock, nose, lips, and having a pencil neck. And apparently coming from a place with little light...noting the big black eyes...and the fact that very few alien abductions happen in broad daylight...
