Eben

Ebens are a race of beings who come from the planet Serpo in the Zeta Reticuli system, these beings apparently made contact with the governments of Earth and had an ambassadorial exchange. The exchange took place in the mid 1960s, where Colonel McKeever was in charge of the operation. McKeever was ordered to keep a diary of his experience jumping and traveling through wormholes to Serpo. The it was a small group, some of which came back, some never returned, and others chose to stay in Serpo. The Ebens arrived in 1947 in a crash near Roswell, New Mexico. Richard Doty did a detailed interview with Doctor Albert Greer in regards to what happened with the crash recoveries of 1947 and 1949. Its also has been said and known that they are watching the human race from afar and that the Eben's can disguise themselves as our human race so it would be hard to recognize them in their original form.
