According to http://www.serpo.org/release1.php, In 1965, there was a government exchange program with aliens which was called the Zeta Reticuli Exchange program. 12 military personnel were carefully selected. They were trained, vetted and carefully removed from the military system. The 12 were skilled in various specialties. The Zeta Recticular star system is approximately 37 light years from earth. It took the team, in an Eben craft, nine months to travel the distance.
By referencing http://www.serpo.org/release2.php, Planet Serpo, where the Eben alien race lives, is located within a solar system of the Zeta Recticular Star System. The planet has two suns but their angles were small and allowed some darkness on the planet depending on one's location. The planet was tilted which allowed the northern part of the planet to be cooler. The planet was a little less than Earth's size. The Eben alien civilization was estimated to be about 10,000 years old. They evolved from another planet, not on Serpo. The original home planet of the Ebens was threatened with extreme volcanic activity.
The Ebens had to relocate to Serpo in order to protect their civilization. This occurred some 5,000 years ago. The Ebens had a great interplanetary battle with another race about 3,000 years ago. The Ebens lost many thousands in their battle. The Ebens completely eliminated all of their enemies. The Ebens have never fought another war since. The Ebens have been space travelers for the past 2,000 years. They first visited Earth about 2,000 years ago.
There is a lot to consider here but we must first open our eyes to see what is really going on in this world and imagine that the possibilities are endless to achieve in our progression as human beings. A very interesting notion and good to know that they released this information according to the policy of declassified information over a period of time.
