What are UFOs?
UFOs are unidentified flying objects, but no one really knows what they are. Many researchers (called “ufologists”) have theories about what UFOs might be, but because no one can examine a UFO in a scientific laboratory, all of these ideas are really only educated guesses. We can offer a definition of UFOs, however, that you may find useful when you study the subject: A UFO is the reported sighting of an object or light seen in the sky or on land, whose appearance, trajectory, actions, motions, lights, and colors do not have a logical, conventional, or natural explanation, and which cannot be explained, not only by the original witness, but by scientists or technical experts who try to make a common sense identification after examining the evidence.
