greys are usually the aliens associated with abduction victims. there motives, at this time, are not clear to us. they seem to be using us humans as their own personal test tube, the reasons:????
there is a conspiracy theory that has to do with the government and the greys. it is said that the greys crashed one or more of their ships, and it was recovered by the U.S. government. the government then made a secret treaty of allowing the greys to abduct human in return for their technolgy. it is said that the greys d i d n o t keep their end of the deal.
the most commonly seen grey is 2-4 feet tall, very slender and delicate looking, small being and light weight. deep black eyes with no pupils, and almost vestigial mouth and nose, a very large head and pointed chin. the skin color can vary from dark- light grey, light tan-dark tan, white-pale white. they are described to be hairless.
there is another type of grey that is said to look about the same, but about 6 inches taller, and with eyes like large black buttons and round. these greys are said to give orders.
there have also been reports of a cross bred grey/human race. they are not exactly grey and not exactly human.
