The US government, through a Pentagon report, has stated that there is no evidence of UFOs or aliens, attributing most sightings to misidentification. Despite this, public perception may not change, influenced by media and entertainment content. Researchers also noted a persistent belief in secret alien research, which the report debunked, along with mistaken identifications of new technologies contributing to UFO sightings since the 1940s. The report concluded that no evidence of extraterrestrial technology exploitation exists.
