Project SERPO and The Zeta Reticuli Exchange Program. So did this really happen? Was there really an exchange program between the inhabitants of the two planets, Earth and Serpo? Twelve American astronauts, 10 men and two women, were selected for the experiment and they were sent to the Planet Serpo in an exchange program with the planet Earth.
Perhaps an RV session could be planned for an investigation into it for the truth?
