UFO phenomena refer to sightings of unidentified flying objects that cannot be easily explained. These objects are often reported as unusual lights or shapes in the sky, leading to speculation about their origins. While many sightings can be attributed to natural or man-made sources, some remain unexplained, sparking interest in the possibility of extraterrestrial life. The study of UFO phenomena includes investigations by various organizations, such as the U.S. government and private research groups. These investigations aim to gather evidence, analyze sightings, and determine whether any of these objects represent advanced technology or potential threats to national security.
