Steven M. Greer

Early life and background

Steven Macon Greer was born in 1955 in Charlotte, North Carolina. By his own account, he had two formative UFO encounters — one at age eight, another at eighteen — that set him on a lifelong path toward extraterrestrial research. In the early 1970s, before pursuing medicine, he trained and worked as a teacher of Transcendental Meditation, eventually directing a meditation organization. That background in contemplative practice would later resurface directly in his UFO work: Greer's signature contact methodology blends meditation technique with UFO field investigation, an unusual synthesis that sets him apart from the radar-data-and-witness-affidavit approach of most mainstream ufology.

He went on to earn a B.S. in biology from Appalachian State University in 1982 and an M.D. from the James H. Quillen College of Medicine at East Tennessee State University in 1987, receiving his Virginia medical license in 1989.

Medical career and the turn to ufology

Greer practiced as an emergency room physician for roughly a decade, working through the late 1980s and 1990s. In 1998, at what by most accounts was the peak of a stable medical career, he retired from clinical practice entirely to devote himself to UFO research and disclosure activism. He has framed the decision as a matter of priorities: if extraterrestrial contact and its cover-up were real and as consequential as he believed, no other work could compete for his time. The move from respected physician to full-time ufologist has been a recurring point both for admirers, who cite it as evidence of sincerity, and critics, who note that credentialed authority does not by itself validate extraordinary claims.

CSETI and the CE-5 protocol

In 1990 Greer founded the Center for the Study of Extraterrestrial Intelligence (CSETI), an organization built around a deliberately different premise than most UFO research groups: rather than passively cataloguing sightings, CSETI would attempt active, human-initiated contact. Greer coined the term "CE-5" — Close Encounter of the Fifth Kind — to describe this, extending J. Allen Hynek's original close-encounter classification scale (which stopped at the third kind, contact with occupants) into a category of deliberate, bidirectional human outreach. CE-5 field sessions typically combine group meditation, specific light and radio signaling protocols, and structured 'sky-watch' documentation, conducted at sites Greer's organization judged favorable for contact. CSETI claims to have compiled testimony from thousands of witnesses, including what Greer describes as more than 3,000 pilot sightings and upward of 4,000 alleged landing-trace cases, though these figures rest on CSETI's own internal case files rather than independently audited data.

The Disclosure Project and the 2001 National Press Club conference

In 1993 Greer founded The Disclosure Project, a nonprofit devoted to pressuring the U.S. government to release what he asserts is suppressed knowledge of extraterrestrial contact and reverse-engineered propulsion and energy technology. Greer gave the project an early media boost by appearing on Larry King's October 1994 special The UFO Coverup?, but its defining moment came on May 9, 2001, when Greer convened a press conference at the National Press Club in Washington, D.C. More than twenty retired military, intelligence, and FAA officials gave on-the-record testimony describing UFO encounters and alleged government secrecy, and the event was carried live on C-SPAN. It remains one of the most widely cited moments in the modern disclosure movement — occurring, notably, just four months before the September 11 attacks reshaped the American security landscape and, with it, public appetite for stories about classified government secrets.

The event's legacy is genuinely contested. Supporters point to the caliber and number of witnesses as unprecedented for a UFO event, lending institutional weight rarely seen outside government-run inquiries. Critics counter that credentialed testimony is not the same as verified evidence: none of the extraordinary claims raised at the 2001 conference — active government possession of extraterrestrial craft, chief among them — were subjected to independent cross-examination or documentary corroboration, and none have since been substantiated by any official investigation, including the post-2017 wave of Pentagon UAP disclosures.

Documentary filmmaking and the Atacama skeleton controversy

Greer's reach broadened considerably through film. In 2013 he co-produced Sirius, directed by Amardeep Kaleka and narrated by Thomas Jane, which laid out his broader case for extraterrestrial contact, free-energy suppression, and government secrecy. The film's centerpiece was the so-called Atacama skeleton, or "Ata" — a roughly six-inch humanoid specimen found in Chile's Atacama Desert, with an elongated skull and unusual bone structure that Greer presented as potential physical evidence of a non-human being. Around 2012–2013, with permission from the specimen's owner, Greer supplied a bone marrow sample to Stanford immunologist Garry Nolan for genetic sequencing, and Sirius previewed Nolan's preliminary findings as ambiguous and tantalizing.

The question was ultimately settled outside Greer's control. In 2018, Nolan and colleagues published a peer-reviewed whole-genome analysis in Genome Research concluding that Ata was unambiguously human — a fetus or infant, likely of local Chilean ancestry, whose severe skeletal deformities were caused by mutations across seven genes governing bone growth (a rare and previously undocumented combination linked to skeletal dysplasia). Coverage in outlets including National Geographic and the Seattle Times treated the finding as a poignant, medically explicable story of a child's remains — and, implicitly, as a debunking of the film's central visual hook. Greer disputed the study, arguing it used outdated sequencing methods and lacked adequate controls, but the peer-reviewed genetic consensus has stood. The episode is widely regarded, even among some sympathetic to UFO research, as a serious blow to Greer's evidentiary credibility: skeptic commentator Robert Sheaffer, longtime "Psychic Vibrations" columnist for Skeptical Inquirer, characterized Sirius as long on assertion and short on verifiable substance well before the genetic study closed the question.

Greer followed with Unacknowledged: An Exposé of the World's Greatest Secret (2017), directed by Michael Mazzola and narrated by Giancarlo Esposito, which reached a much larger digital audience — briefly topping iTunes' documentary chart — by packaging his claims about crash retrievals, back-engineered technology, and a supposed shadow government (which he calls the "secret Above Top Secret" apparatus) for a Netflix-adjacent streaming audience. He continued with Close Encounters of the Fifth Kind: Contact Has Begun (2020), which drew a notably cooler critical reception, with several reviewers describing it as unfocused, and The Lost Century — and How to Reclaim It (2023), his most recent feature documentary.

CE-5's afterlife

Whatever its evidentiary shortcomings, the CE-5 protocol has proven to be Greer's most durable practical export. Long after CSETI's initial 1990s prominence faded from mainstream coverage, small independent "CE-5 contact" groups continued to form around the world, running group meditation and sky-watch sessions modeled directly on Greer's original methodology, often coordinated informally online rather than through CSETI itself. The practice has occasionally resurfaced in popular culture — including brief mainstream press interest tied to celebrity participants — well outside the context of Greer's own organizations, suggesting that the protocol resonated as a participatory ritual independent of whether its underlying contact claims are credited.

Published works

Greer has also written extensively, producing Extraterrestrial Contact: The Evidence and Implications (1999), Hidden Truth, Forbidden Knowledge (2006), and Unacknowledged: An Exposé of the World's Greatest Secret (2017), the book companion to his film of the same title. These works lay out his combined case: witness testimony compiled through CSETI and the Disclosure Project, claims about suppressed energy technology, and a broader argument that public disclosure is being deliberately blocked by unaccountable elements within military and intelligence bureaucracies — what he has termed a "secret government" independent of formal executive oversight.

Later activity and continued advocacy

Greer has remained active into the 2020s, holding a further press conference at the National Press Club on June 12, 2023, where he presented claims of illegal, unacknowledged "black budget" UAP programs, was joined by self-described military whistleblowers — including a Marine who alleged witnessing a human-made UAP transferring weapons and narcotics near Indonesia in 2009 — and announced plans for a civilian RICO lawsuit targeting the programs he alleges exist. As with the 2001 event, the claims generated significant online attention but no independent corroboration.

Greer has also positioned himself somewhat apart from the post-2017 mainstream disclosure movement associated with figures like Luis Elizondo and the Pentagon's official UAP task forces — first the AATIP program and later the All-domain Anomaly Resolution Office (AARO). Where Elizondo and allied figures have generally worked to legitimize UAP research from inside government and defense-adjacent channels, Greer has repeatedly argued that officially sanctioned disclosure efforts are themselves a controlled, partial narrative — engineered, in his telling, to manage public perception rather than deliver a genuine reckoning with what he asserts the government already knows. That stance has put him at odds with parts of the UFO research community that see the 2017–2023 wave of Pentagon transparency (congressional hearings, the declassified Navy videos, AARO's historical review) as hard-won and incremental progress rather than theater. Greer, by contrast, continues to frame disclosure as something that must be forced from outside government rather than granted by it, a position consistent with his activism since the 1990s.

Reception and legacy

Greer occupies an unusual position in UFO history: he is simultaneously credited with orchestrating one of the most institutionally impressive UFO media events ever staged (the 2001 National Press Club conference) and with promoting one of the most thoroughly debunked pieces of purported physical evidence in the field's recent history (the Atacama skeleton). His CE-5 protocol has proven durable and influential as a grassroots practice, spawning small "CE-5 contact" groups worldwide who continue to meet for group sky-watches decades after CSETI's founding. At the same time, his specific evidentiary claims — pilot sighting counts, landing-trace statistics, suppressed free-energy technology, and the details of alleged crash retrievals — remain almost entirely unverified outside his own organizations, and his handling of the Atacama case in particular has left a lasting mark on how skeptically outside observers weigh his testimony. He remains one of the most recognizable and polarizing figures in contemporary ufology: a serious early mover on government transparency who also, by his critics' account, repeatedly overpromised on evidence that did not hold up.

That duality extends to how other researchers in the field treat him. Some UAP investigators who otherwise argue for taking the topic seriously as a matter of national security and scientific inquiry have gone out of their way to distinguish their work from Greer's, wary that his more sweeping claims — a fully operational secret space program, systematic multi-decade ET contact, free energy hidden from the public — invite exactly the ridicule that mainstream disclosure advocates have spent years trying to shed. Others credit him as a forerunner who normalized public conversation about credentialed military witnesses years before it became a subject fit for congressional hearings and mainstream news coverage. Both readings are defensible, and the tension between them is, in a sense, the story of Greer's career: a figure whose organizing instincts and media savvy repeatedly got serious institutional attention for the UFO question, matched by a persistent willingness to stake his credibility on claims — the Atacama skeleton chief among them — that did not survive scrutiny.
