There have been supposed alien sightings for centuries. These observations of "unidentified flying objects," or UFOs, have periodically surged, such as during the late 1940s and early 1950s as the Cold War began. There have been more sightings since the early 2000s, driven by advances in sensors and cameras that capture images in real time.
