Man has been here 2-million years, had something which has looked like civilization the past 10,000 years just after the last ice age ended.
It's been a good run, the alien experiment has run it's course. Time for us to be transplanted somewhere - up there.
The grays are only the slaves of the other 10 alien races which look over us. They will do what they are told. We are at their mercy, our actions have sealed our fates.
..............and the meek shall inherit the Earth.
