"Alien threat theory" is a popular theory in current academic circles. For example, Stephen Hawking, a British physicist and mathematician, has repeatedly warned that aliens may invade the earth for resources; For another example, the British evolutionary biologist Simon Morris once wrote: "The evolutionary process of aliens may be the same as Darwin's theory; This means that aliens may be very similar to us. Frankly speaking, they may even be violent. "

20111/in October, experts from many famous universities such as Cambridge University even called on governments to come up with action plans to deal with the problem that people on earth were attacked by aliens. They also called on the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) to deal with "alien affairs" in this regard to prevent alien invasion. ?

For a long time, many sci-fi works have described the scene of aliens attacking people on earth. For example, the sci-fi movies "Battle of Los Angeles", "Super Battleship" and "Men in Black 3" recently released around the world are full of slogans against alien invasion. Aliens are demonized; Their images are often ugly, horrible and lacking in humanity. However, some experts don't think that aliens will attack people on earth; They show that they do not pose a threat to us from the intelligence, reason and technical level of aliens, and even from the psychological effect of human beings on aliens.

Zhou Haizhong, a mathematician and linguist in China, pointed out in his paper Cosmology Linguistics: A New Frontier Discipline published in 1999 that there is no need to worry about the threat of aliens at all, because as long as they are advanced intelligent creatures, their rationality determines that they must treat other intelligent beings with discretion; Aliens and earthlings can live in peace, friendly cooperation and common development in the future. ?

David Morrison, an American astronomer, said in an interview with the media recently, "If a civilization can exist for hundreds of thousands of years, it will certainly solve a series of problems we face, so there is no need to invade the earth, plunder resources and kill mankind." He refuted the "alien threat theory" and even thought that aliens were "messengers of peace", friendly and lovely, and said humorously: "If aliens visit, I will treat them well." ?
