| Status | UNPROVEN |
| Summary | Proponents claim that governments, especially the US, suppress evidence of extraterrestrial UFOs and may be in communication with aliens. This theory gained traction in the 1940s and 1950s with early flying saucer sightings and books like Donald Keyhoe's. Mainstream scientists and investigators find no verifiable evidence for such cover-ups. |
| Origin | Late 1940s, United States, following the Kenneth Arnold sighting and subsequent flying disc craze. |

| Evidence / consensus | No verifiable evidence supports the claim of a government cover-up of alien visitation. Most sightings are explained by mundane phenomena, and official studies like Project Blue Book found no evidence of alien involvement. |
