The first UFO sighting was reported as 1878 65438+ 10. At that time, an American farmer saw a disc-shaped flying object over Texas. American 150 newspapers published this news and called it a UFO. 1June, 947, an American entrepreneur Kay? When Arnold was flying in a private jet near Hexiao Leshan in Huasheng, he found nine disks flying at high speed in the air. This incident was reported by almost all American newspapers and once again attracted the attention of the world. After that, reports of UFO sightings poured in, forming a big "UFO fever".
What exactly is a flying saucer? So far, there is no conclusion. Because UFO is not a reproducible phenomenon, or a frequent phenomenon, it has great contingency, so there is no unified inspection standard. So far, there is no absolutely authoritative view in the world. Scientists with a negative attitude believe that many eyewitness reports are unreliable, UFOs do not exist, and they are only human illusions, or eyewitnesses misunderstand some natural phenomena, while scientists with a positive attitude believe that UFOs are real phenomena and are being proved by many facts. However, many UFO experts do not think that UFOs are spaceships driven by aliens. They believe that believing in UFOs should not be confused with believing that UFOs are driven by aliens. But a few UFO experts insist on the "alien theory"
I'm afraid the debate about UFOs will continue. What a UFO really is can only be proved by facts in the future. People expect it to have a correct explanation in the end.
