UFOs, or unidentified flying objects, have been reported throughout history. While there is no scientific evidence to support the existence of flying saucers or aliens, many people continue to report seeing strange objects in the sky. Some of the earliest recorded UFO sightings date back to ancient times, with many different cultures and civilizations describing objects in the sky that could not be easily explained. In more recent history, UFO sightings became more common and were often reported in the news media. Some of the most famous UFO sightings include the Roswell UFO Incident in 1947, the Rendlesham Forest Incident in 1980, and the Phoenix Lights in 1997. Despite these sightings, there is no conclusive evidence of the existence of aliens or flying saucers.
