When people think about unidentified flying objects (UFOs), they tend to think of flying discs piloted by gray beings with large heads and enormous eyes. They also might believe that these sightings only started relatively recently and that belief in UFOs is some sort of modern phenomenon brought on, perhaps, by the very justifiable fears of a nuclear age. But a study of UFOs quickly reveals that people have been reporting the existence of unidentified flying objects since the beginning of recorded history, and perhaps a lot longer than that. Modern Ufology focuses on mysterious lights on Ceres or tales of alien abduction, but this wasn't always the case, and looking at how the beliefs in the UFO phenomenon have changed or stayed the same can shed light on how culture and belief changes over time. One does not have to believe humans are actually being visited by aliens from another planet to recognize the importance of UFOs in society. Any widespread belief that endures for centuries is worthy of study, and as always, cases exist that can't be explained away simple superstition. Most everyone in America is familiar with theories about UFOs, or “flying saucers” as they were often called then, but even this name dates back only to 1947. Before that time, they were called “ghost rockets” or “ghost airplanes” or “ghost airships.” Before the age of flight, the flying objects were called various things such as “flying chariots.” No matter what terminology is used, every generation has clearly had its own belief that mankind is not alone.
