Unidentified flying objects (UFOs) are now commonly referred to as unidentified aerial phenomena (UAPs) . The term UFO was added to the worlds lexicon by the U.S. Air Force in 1952, just five years after the Roswell sighting. Since then, the term UFO has been affiliated with the belief that there is extraterrestrial life or aliens outside Earth. People have called those flying objects all sorts of names, such as flying saucers, hovering lights, and floating discs. However, its important to note that UFOs dont necessarily mean aliens are visiting Earth, either. UFOs can also refer to other objects in the sky such as weather balloons or drones. While both acronyms refer to the same unidentified events reported in the sky, government agencies began using UAPs instead of UFOs in 2021 in hopes of muting some of the conspiracies flooding the public.
