EBENs (Extraterrestrial Biological Entities, Not [earth-]Native) is the designation used in classified context for the beings involved in the alleged Project Serpo — a claimed secret United States government exchange program in which twelve US military personnel traveled to the EBEN home planet for an approximately 13-year stay (1965–1978), while one living EBEN survivor of the Roswell crash was returned to his home system. If accurate, Project Serpo represents the most consequential event in human history: confirmed interstellar contact and physical exchange between Earth humanity and an extraterrestrial civilization.
EBEN physical description from the Serpo disclosures and related testimony:
The alleged origins of Project Serpo lie in the Roswell Incident of July 1947. Per the Serpo disclosures, one or two EBENs survived the crash(es) near Roswell. Communication was established with the surviving EBEN through a device recovered from the craft. Over the following years, radio/signal contact was established with EBEN representatives. Negotiations ensued over what would become the exchange program.
Under what is described as an agreement formalized during the Eisenhower administration (variously dated to 1954 or later; potentially the "Greada Treaty" or a subsequent arrangement), the terms of the exchange were negotiated: twelve human military volunteers would travel to the EBEN home planet (designated Serpo) in exchange for technology transfer and continued communication. One living EBEN would be returned to Serpo. The agreement also specified protocols for ongoing communication and further contact.
Beginning in November 2005, an anonymous source identified only as "Request Anonymous" — later identified by researchers as a high-level intelligence community insider — began releasing documents about Project Serpo to UFO researcher Victor Martinez, who distributed them through an email network of researchers. The documents included mission briefing materials, team member diaries (edited for security), EBEN biological descriptions, and Serpo civilizational data. Bill Ryan of Project Camelot and researcher Robert Collins investigated the disclosures and found significant internal consistency and what they described as credible classified terminology consistent with genuine intelligence documents. Richard Doty, a former Air Force Office of Special Investigations (AFOSI) agent, was identified by some researchers as involved in the disclosures — a connection that both lends and complicates credibility, given Doty's documented history of intelligence-community UFO disinformation operations (the Paul Bennewitz case).
Team diaries, as released through the Serpo disclosures, describe EBEN civilization on Serpo:
This profile presents the Project Serpo disclosures as significant claimed testimony in the UFO/NHI literature without endorsement of their accuracy. The involvement of Richard Doty — a documented AFOSI agent with a known history of UFO disinformation operations — creates an unresolved credibility challenge that cannot be dismissed. The Serpo disclosures are presented here as an important case study in the distinction between authentic disclosure and potential disinformation. No conclusions about the literal reality of described events or entities are made herein.
