The acronym UFO stands for Unidentified Flying Object. It refers to any object or light seen in the sky that cannot be readily identified or explained. UFOs are often associated with extraterrestrial spacecraft or alien activity, although there is no concrete evidence to support this claim. UFO sightings have been reported worldwide since the mid-20th century, with various theories and explanations proposed. Some suggest that UFOs could be advanced military aircraft or experimental prototypes, natural atmospheric phenomena, reflections or illusions, or even hoaxes. The existence and nature of UFOs remain a subject of curiosity and debate, attracting scientific, governmental, and public interest.
