Physician, UFO disclosure advocate, filmmaker and founder of the Disclosure Project. Explore Steven Greer’s life, the witnesses he has brought forward, the CE5 contact movement, his documentaries and books, and the questions that remain open to independent scrutiny.
Steven Macon Greer is an American physician who became a prominent figure in the modern UFO/UAP disclosure movement. He founded the Center for the Study of Extraterrestrial Intelligence (CSETI) and the Disclosure Project, and later promoted CE5—his approach to alleged human-initiated contact with extraterrestrial intelligence.
Greer trained and worked as an emergency physician before making UFO research, public advocacy, documentary production and contact initiatives his principal public work. His medical background is part of his biography; it does not independently validate his claims about UFOs or hidden programmes.
He argues that governments and private contractors possess significant undisclosed information about non-human intelligence and advanced technologies. He also promotes peaceful contact and says consciousness and meditation can be part of that process. These are his stated positions, not conclusions established by mainstream scientific consensus.
Editorial guide: this page distinguishes established biographical facts and public events from Greer’s own statements, witness testimony, interpretations and claims that have not been independently verified.
Greer’s public story combines a conventional professional career with accounts of personal experiences, meditation, contact encounters and a long campaign for disclosure.
Greer has described experiencing a UFO sighting when young and developing an interest in meditation and consciousness. These accounts are part of his own autobiographical narrative rather than independently documented events.
Greer trained in medicine and worked in emergency medicine. Official biographies describe him as having later retired from clinical practice to focus on disclosure advocacy, CSETI, CE5 and related projects.
He founded the Center for the Study of Extraterrestrial Intelligence (CSETI), developing protocols and organising expeditions intended to investigate and initiate peaceful contact with alleged non-human intelligence.
Greer began collecting and publicising accounts from people who said they had worked in military, intelligence, aviation or government roles and had information about UFO incidents or secrecy.
Greer organised a widely circulated Washington, D.C. event featuring witnesses describing alleged encounters, recovered materials and official secrecy. The event is a key milestone in the contemporary disclosure movement; each witness account still needs to be evaluated individually.
Films including Sirius, Unacknowledged, Close Encounters of the Fifth Kind, The Cosmic Hoax and The Lost Century brought his claims and advocacy to a wider international audience.
The Disclosure Project Intelligence Archive was announced as a public research resource in 2024. Greer’s official site has since featured podcasts, new media projects, interviews and anniversary events.
For precise biographical details, consult Greer’s own biography and publications alongside independent reporting. Some online biographies differ in the number and naming of his books and projects.
A campaign to bring UFO-related testimony and documents into public view—and one of the central pillars of Greer’s work.
Collect testimony. Publish records. Demand public accountability.
Greer says the project has interviewed or gathered testimony from military personnel, intelligence staff, pilots, government employees and contractors. Its most visible event was the May 2001 National Press Club presentation in Washington, D.C.
Witnesses have described unusual objects, radar encounters, alleged crash retrievals, secrecy and purported advanced technology. A witness’s job title or sincerity does not automatically establish that every interpretation is correct; records, dates, corroboration and alternative explanations matter.
Greer’s archive project aims to organise decades of documents, video, photographs and research material. The official site describes it as an evolving resource that continues to need cataloguing and refinement.
Archive information →The event placed a group of witnesses before cameras and journalists. The testimony is historically important to UFO disclosure culture, but is not the same thing as a formal finding by a government or scientific body.
Find the full conference on YouTube →Useful questions include: Is the original document available? Is the witness named and speaking first-hand? Can dates and locations be checked? Are there independent records or plausible conventional explanations?
Official document library →Greer’s term for protocols intended to facilitate peaceful, human-initiated contact with alleged extraterrestrial intelligence.
CE5 sessions commonly involve groups meeting in quiet outdoor locations, meditation, focused intention, visualisation and sometimes skywatching or the use of apps and audio materials. Greer presents consciousness as an important element of contact and encourages participants to approach the subject peacefully.
Participants may report lights, unusual objects or meaningful experiences. Such reports can be personally significant, but they do not by themselves establish an extraterrestrial origin. Satellite trains, aircraft, planets, drones, atmospheric effects, expectation and misidentification are among the possibilities investigators should consider.
Greer’s documentary Close Encounters of the Fifth Kind: Contact Has Begun introduces the approach through interviews, participant stories and footage presented by the filmmakers.
Greer’s films combine his own narrative with interviews, witness accounts, documents and interpretations of UFO events. The summaries below describe each film’s subject and link to official or video resources; the claims presented in the films remain subject to independent evaluation.
Follows Greer’s work on disclosure, witness testimony and alleged advanced energy and propulsion technology. It also examines the Atacama humanoid, a small skeletal specimen that became the subject of public debate over its origin and biological identity.
Explores the Disclosure Project’s witness accounts, classified documents, UFO footage and Greer’s argument that information about non-human intelligence has been concealed by covert programmes.
Introduces CE5 and the idea that people can initiate peaceful contact. It features participant experiences and interviews with advocates and researchers associated with consciousness studies and UFO research.
Greer argues that some official and media narratives about UFOs deliberately mislead the public, and that some reported craft may be human-made. The film presents his interpretation of disclosure and alleged disinformation.
Connects UFO secrecy with Greer’s claims about suppressed energy technologies and the consequences of delayed technological progress. The proposed technologies and suppression narrative should be assessed against independently reproducible evidence.

Greer is an influential advocate in a subject where many claims are disputed and the available evidence varies widely. Serious research should be curious without assuming the conclusion in advance.
The existence and dates of public press conferences, film releases, books, interviews and archived documents can be checked directly. Some witness identities, employment histories and contemporaneous records can also be investigated independently.
Assertions about extraterrestrial visitors, recovered craft, secret programmes, suppressed energy systems or a coordinated global cover-up require evidence that is independently testable. Repetition across documentaries or interviews is not independent corroboration.
Reports from CE5 gatherings should include exact time, location, direction, duration, weather, camera settings and any flight or satellite information available. Independent observers and unedited original footage can help rule out ordinary explanations.
The Atacama humanoid discussed in Sirius prompted claims about unusual origins. A responsible account should consult published genetic and anatomical analysis rather than treating promotional descriptions as scientific consensus.
These official pages and primary links are useful starting points. Where a source presents Greer’s own position, read it as an attributed account and compare it with independent evidence.
Editorial standard: this dossier separates biography and verifiable public activity from personal testimony, interpretation and unverified claims. Dates, availability and current-event listings should be rechecked before publication.
