heres a piece about it that i cut and paste wholesale from another website...hehe shameless me.
"I was told the Greys were originally benevolent beings that were genetically bred as scouts/scientists/workers. The biengs that bred them set them free and they chose Pleides and Arturus as their home.
They were captured by the malevolent breed of Reptilians and enslaved. The method of enslavement used was removing their reproductive organs. The Reptilian then bred their genes into these greys and produced a malevolent breed of grey that they duplicated by cloning process. These malevolent breeds of greys were dispersed into places such as ZETA RETICULI, Bellatrax, and Earth.
I was also told that these greys have tried to regain their freedom by crossbreeding themselves with us because the Reptiles control their duplication therefore controlling their entire existance. Which is why many of us have been abducted and our reproductive systems studied and used.
There are still breeds that work hand in hand with the reptile. Such as the Zeta Reticulan.
There are breeds that were here before Humans, and they want this place to themselves but they need our genetics to live above ground [out of water] in the sunlight. "
though of course the guy doesn't say who told him. Must be an official; whitehouse leak.
