Why did the Three-Body People attack the Earth?
In Liu Cixin's science fiction novel," The Three-Body Problem ", the reason why the Three-Body Problem people attacked Earth was that the long-term war and civilization conflict had led to distrust and hostility between the Three-Body Problem civilization and the Earth civilization. In the universe of the Three-Body Civilization, due to the frequent wars and disasters between the solar systems, the civilization was unstable and divided into different civilizations. Among them, the " Dark Forest Law " of the Three-Body Civilizations believed that there were great dangers and threats between civilizations in the universe, so each civilization would try their best to maintain secrecy and avoid conflicts with other civilizations. In the novel, the Earth civilization was also threatened by the Three-Body Civilization. Due to the discovery of the Three-Body People on Earth, a fierce war broke out between the Earth civilization and the Three-Body Civilization. In this war, Earth's civilization paid a huge price, causing civilization to regress for decades. At this time, an expedition team from the Tri-body Civilization accidentally discovered Earth and tried to enter the Earth Civilization through deception and infiltration. In the end, the Three-Body People successfully destroyed the infrastructure and civilization development process of Earth civilization by establishing bases on Earth, attacking and invading, forcing the Earthlings to submit to the rule of the Three-Body Civilization. Therefore, the reason why the Three-Body People attacked Earth was because of the long-term war and civilization conflict, which led to the distrust and hostility between the Three-Body Civilization and the Earth Civilization, as well as the invasion and destruction of the Earth Civilization by the Three-Body Civilization.
