Why is most people s first impression of aliens aggressive and possessive?

If you have watched Liu Cixin's "The Three-Body Problem", you may be able to understand this, which talks about a law called.

The Law of the Dark Forest. This means that if you are a hunter and you are in a completely dark forest, you can't figure out whether it is a man or a beast on the other side, or if you want to kill the bad guys who want to kill you, if you want to survive, the safest way is to shoot the other person first, no matter what the reason is.

In the same way, the universe is like a dark forest, human beings are like a hunter with a gun, and every civilization is like a hunter with a gun, carefully moving forward in the jungle like a ghost, gently brushing away the branches that stand in the way, trying not to make the slightest sound in his footsteps, even breathing must be careful, he must be careful, because the jungle is full of hunters with guns like you, and if he finds the traces of others, there is only one thing he can do: shoot and destroy them. In this forest, others are hell, eternal threats, and any life that reveals its existence will be quickly wiped out, this is the law of the universe.

It is not difficult to conclude that if there are aliens, the first reaction of human beings must be unfriendly or unfavorable to human beings, and at the same time, many scientists, including Stephen Hawking, oppose human beings revealing their position to the universe, and warn human beings not to easily try to contact aliens, because you don't know what the other party's civilization is like, on the scale of cosmic time, human beings who have only evolved for millions of years are only the extremely rudimentary stage of civilization development.

Although we are curious about aliens, we also have an unknown fear of aliens in advanced civilizations, and we don't know if they are good or bad. Because we belong to different civilizations, just like after Columbus discovered the New World, the "higher civilizations" invaded and killed the "lower civilizations", and tortured the Indians. This also indirectly reflects that human beings have reflected the desire for invasion and possession to aliens, for fear that more advanced alien civilizations will invade us.

This is the fear of the unknown that humans have. The technological level of alien civilizations should theoretically be far higher than that of humans. From ancient times to the present, human beings have experienced wars in the course of their development, so they subjectively believe that aliens should be aggressive and possessive.

This is all misleading in the TV series, because the aliens in the TV series are all here to invade the earth.

Because there are many literary works of alien invasion of the earth, many people will be affected, so most people's first impression of aliens is aggressive and possessive.
