Background and documented career
Greer founded the Disclosure Project and CSETI. His biography describes retirement from emergency medicine; contemporary reporting also identifies him as a physician. That professional background does not independently validate aerospace or extraterrestrial claims. [1] [2]
What has been claimed or reported
His April 2001 project statement describes recording and editing witness interviews for public disclosure. He sought congressional hearings, declassification and access to alleged advanced energy systems. The archive records what interviewees said, rather than establishing every account as fact. [1] [2]
Greer also helped obtain samples from the Atacama skeleton. His 2013 account called it unexplained while explicitly declining to identify it as extraterrestrial; he disputed the later genetic study in a 2018 letter. [4] [6]
What the public record supports
Contemporary reporting confirms the May 2001 National Press Club event and its call for hearings. The Club also listed a twenty-fifth-anniversary event for May 2026, documenting the campaign's continuing public activity. [2] [3]
Limits, disputes and open questions
The 2018 genome study identified the Atacama remains as human. A subsequent scientific critique disputed interpretations of skeletal abnormalities and research ethics, but likewise described a human fetus. Disagreement about pathology therefore supplies no positive evidence of an alien origin. [5] [7]
A notable venue is not scientific validation: the National Press Club explicitly said it neither sponsored nor endorsed the 2026 event. Individual witness accounts and Greer's wider conclusions must be evaluated separately. [1] [3]
