World UFO Day is celebrated on July 2nd each year to raise awareness about unidentified flying objects and the possibility of extraterrestrial life. The day encourages people to share their experiences and knowledge about UFO sightings, as well as to promote discussions about the existence of life beyond Earth. The origins of World UFO Day can be traced back to the 1947 sighting of a UFO by pilot Kenneth Arnold, which sparked public interest in the phenomenon. Events often include sky-watching, film screenings, and discussions about famous incidents, such as the Roswell Incident and the Phoenix Lights.
