Dr. Steven M. Greer discusses his groundbreaking Congressional briefing on extraterrestrial intelligence and UFO disclosure efforts. As founder and director of CSETI, Greer reports on a closed briefing held for members of Congress, their staff, and National Academy of Sciences representatives featuring witnesses with top-secret clearances willing to testify under oath about UFO encounters. The briefing included military personnel, technicians, and government officials who have directly handled extraterrestrial debris containing hieroglyphic-like inscriptions and witnessed unambiguous UFO events. Greer reveals that Harvard Observatory has received intelligently generated signals ruled out as Earth-based satellites or natural phenomena, representing potential extraterrestrial communication. He emphasizes that these witnesses, many elderly and in poor health, are courageously coming forward despite potential legal and professional consequences because they believe this information represents the most important development in human history. The briefing excluded lights-in-the-sky reports, focusing instead on physical evidence cases involving recovered materials, direct encounters, and documented electromagnetic effects. Greer expresses frustration with institutional secrecy surrounding extraterrestrial contact while noting that many scientists and government officials privately acknowledge the reality of the phenomenon. His disclosure project aims to break decades of official silence through Congressional testimony under penalty of perjury.
