From the perspective of communism.
The issue of the origin of humanity has always been a topic of concern for everyone. In theology and biology, two systems, creationism and evolutionism, have emerged. No one can convince anyone, but based on rational, scientific, and rigorous attitudes, most people still choose to believe in evolutionism. It's just that this theory still cannot completely convince people, so a seemingly conspiracy theory has emerged, which believes that humans were put on Earth by aliens for some kind of experiment or observation.
However, although this theory can explain the origin of humanity from a certain perspective, it also brings up the question of the origin of aliens - if humans are experiments of aliens, then who are the experiments of aliens?
Recently, the animation and TV series adapted from the novel "The Three-Body Problem" have raised this question to the level of conflict and contradiction between human civilization and alien civilization, as well as the fate of humanity. I haven't read or watched this masterpiece, but I still want to talk about the possibility of alien invasion of Earth based on my understanding of society, politics, and culture. Mainly because our science fiction works can stimulate a lot of people's thinking, but these thoughts may not necessarily become answers or provide references for viewers, so we need to have some discussions for the reference of the pessimists.
We need to know that the evolution process of humanity has taken a long time. If aliens have more advanced technology than humans and can achieve technologies such as space-time jumps and faster-than-light travel, allowing them to navigate freely in the universe, then they must solve the following problems relatively:
First, the political issues between countries.
The Earth we live on is a world composed of multiple continents and islands. There are one or two hundred countries and regions in this world. The political issues between countries are very important. If aliens go through the process of civilization like humans, multiple countries will inevitably be born on their own planet. These countries will have political opposition and different cultures. The interactions between countries often come with various conflicts and contradictions. If a country launches a military action against another planet without authorization, it will inevitably be condemned by other countries. Some peace-loving countries may even send counter-forces to clash with each other.
So, can we say that these countries have no possibility of taking external actions without being invaded themselves?
Of course, if aliens invent faster-than-light spacecraft that can allow them to reach other star systems in a short period of time or even instantly, then their politics must be very harmonious. You should know that the instruments for studying space-time jumps are very expensive in terms of financial and material resources. If the international community cannot reach a consensus, it is generally difficult for a single country to develop them. Even if they are developed, they will immediately be effectively imitated or even banned by prohibition orders, prohibiting other countries from researching again. This is determined by international politics.
In other words, if political unity cannot be achieved, it will be impossible for everyone to agree to launch a war against the outside world. Although this war may not consume as many resources as a highly developed race, everyone must act within a political framework. If anyone goes beyond the line, it is likely to cause international conflicts.
Of course, it is not ruled out that when alien technology has developed to a certain extent and civilization has progressed to a certain extent, they have already achieved a communist civilization, and all kinds of political barriers no longer exist. Only then will they consider launching a war against the outside world to eliminate lower civilizations and leave only their own unique battle.
But since civilization has developed to such an extent, doesn't the so-called dimensional strike seriously undermine the meaning of civilization? Therefore, no matter how the politics of aliens operate, they will not invade. If the communist society of Marxism does not allow oppressive and aggressive behavior, will the higher-level beings be less knowledgeable than a human communist? If they are looking for life in the universe and walking around, they will not use the military at all because there is no military in a communist society. They will only send scientific research teams.
Some people say that although the civilization of aliens is advanced, they lack resources. They want to enter communism by invading and accumulating primitive accumulation of materials and wealth. I find this ridiculous. As a higher-level civilization, don't they know that wherever life exists, such as Earth, there will definitely be resource shortages? Earthlings still need to conduct scientific research and search for materials on alien planets. Don't their technologies know that the reserves of minerals and resources on so many planets in the universe are far more than those on Earth? Instead of coming to Earth to plunder human resources, isn't it ridiculous?
This is the first reason why this possibility is low.
Second, the conflict between religions.
This is the most challenging social issue that our society faces because most problems in the world can ultimately be traced back to two major issues: religion and politics. If aliens have advanced technology, maybe they don't have conflicts between religions, but that doesn't mean they didn't exist in history. So how did they eliminate religious conflicts?
If aliens have advanced technology and have entered a communist society, then according to the inference of Marx and other theorists, the issue of religion will naturally be eliminated. Compared with the religions on Earth, although everyone wants to spread their own beliefs to the world today, they cannot conquer everyone. On the one hand, in a communist society, everyone must have a full understanding of atheism due to the development of science and technology. At the same time, religion itself has a great gene of social conflict, so it will be gradually abandoned as society progresses. In the process of the development of a higher-level civilization, the rejection and criticism of religion will be a social phenomenon of great significance for a period of time. Although we advocate religious freedom today, religion itself is something that needs to be put into an urn. Therefore, if aliens have the ability to disturb humanity, they will definitely not bring religious cognition and religious bias.
This will also be a significant part of the history of aliens. If they have entered a communist society, they will certainly be committed to imparting their experiences to civilizations that are still trapped in religious conflicts, rather than thinking about directly eliminating them.
Third, women's rights, homosexuality, and various distorted gender issues.
I don't know how aliens reproduce, but the most important issue is that sufficient resources can ensure that alien civilizations have the ability to maintain the long-term development of communist society. In other words, the problems caused by misandry brought about by women's rights, the problem of extinction caused by homosexuality, and the various social conflicts caused by the so-called LGBT will be inevitably resolved.
If this problem cannot be solved, human society is likely to be unable to develop for a long time and will be interrupted due to the inability to reproduce offspring, without the need for alien invasion. If the aliens of the higher-level civilization also reproduce sexually, they must solve this problem because this problem is largely related to politics. Of course, the most likely possibility at that time is to use technology for artificial reproduction, which can also edit the genes of offspring to eliminate their selfish genes and implant highly conscious communist genes. In this way, there will basically be no people who destroy communist society, and there will also be no warlords willing to launch wars against the outside world.
We should know that the problem of male-female opposition in modern society is the root cause of the marriage and human resources dilemma of modern people. Our genes make us animals that reproduce sexually, but most people do not want to reproduce through sex, but only care about sex itself, which leads to serious gender conflicts in human society. If this continues for a long time, it will easily cause a shortage of population, and human civilization may not even survive until the early stage of communist society. Therefore, it will be an ethical choice that must be made to edit the racial genes of human beings through technology to eliminate their defects and implant highly conscious communist genes.
Based on the above theories, it can also be argued that a higher-level civilization must go through all of this in order to achieve a unified and consistent social and political ideology, such as entering a communist society.
At this time, the aliens have long had a high level of understanding of the term civilization and will never launch aggression against others, especially against undeveloped civilizations, because they are highly developed, self-sufficient in energy, and have no need to do so.
Imagine, if a higher-level civilization wants to destroy a lower-level civilization that has not yet developed to its level, then this so-called higher-level civilization itself should be destroyed, not to mention that if there is such a civilization in the universe, there must be another civilization of the same level or even higher level. When these highest-level civilizations see middle and high-level civilizations developing towards lower-level civilizations, if they just stand by, it is obviously abnormal. At the same time, when these so-called higher-level civilizations invade lower-level civilizations, will they think that there will be another higher-level civilization watching them?
Some people say that since unification is needed, maybe aliens are more eager to build a communist society as soon as possible, so they come to Earth under various banners to eliminate all humans who do not contribute, and then leave only those who are willing to submit. Isn't this more conducive to building a communist universe?
In fact, this possibility is very slim. A highly developed civilization that has already achieved a communist society will not care about other lower-level civilizations. Even if there is no non-aggression treaty signed by various alien races in the universe, according to the nature of their communist society, they will not have such thoughts because the elimination of these problems requires time for them to achieve it themselves and cannot rely on excessive external force.
Fourth, the issue of race.
This is a fatal problem faced by a few countries. Racism has given birth to reverse racism, Western white leftists, minority ethnic privileges, and oppression between races. Some people may not have thought that in this society, in addition to capitalists oppressing proletarian workers, there are also discrimination and oppression based on racial bloodlines among ordinary people. The issue of race in alien society is definitely more complex than on Earth. Imagine if an alien planet is smaller in size than Earth, it will not give birth to such a developed civilization, or even if it does, it will be extremely internal consumption due to the extreme internal consumption caused by resource competition. It is impossible to develop to a more advanced level. Unless they have enough races, it also means that their population is large, and different races will inevitably create various conflicts due to geographical culture and different skin colors. These problems must be resolved, otherwise it will be difficult to enter a highly developed civilization. We know that the ultimate form of a higher civilization is nothing more than a communist society, in such a society, there is no distinction between white, black, and yellow races, everyone is equal, so no one has the right to command others to do things for themselves, even for common interests, they need to take turns to manage. However, this will also form a managerial class, which is obviously inconsistent with the values of a communist society. Therefore, aliens will definitely not launch aggression against the outside world because aggression itself is not in line with the ideals of a communist society.
At the same time, based on the need to solve the racial problem, aliens must achieve racial intermarriage, racial integration, and genetic modification to eliminate excessive differences in skin color, height, and appearance among all people.
Fifth, the issue of nationality.
This problem is similar to the issue of race, but a nation is ultimately a branch of different cultures and regions under the same race. Therefore, internal conflicts are also normal. Some ethnic conflicts may even cause serious criminal problems. In order for humans to unite, they must learn to solve problems. Respect alone is not enough. The value of a communist society is unity. Either all of them are rejected, or one of them is designated as the only standard.
If aliens can solve these problems, it shows that they are indeed worthy of the title of an advanced civilization. But since they can solve the problems of racial and ethnic conflicts, would they not understand the conflicts between planets? Will they try to eliminate lower races?
Some people say that since unification, maybe aliens are more eager to build a communist society and come to Earth under various banners to eliminate all humans who do not contribute, and then leave only those who are willing to submit. Isn't this more conducive to building a communist universe?
In reality, this possibility is very slim. A highly developed civilization that has already achieved a communist society will not care about other lower-level civilizations. Even if there is no non-aggression treaty signed by various alien races in the universe, according to the nature of their communist society, they will not have such thoughts because the elimination of these problems requires time for them to achieve it themselves and cannot rely on excessive external force.
Sixth, the issue of class.
The so-called class mainly refers to capitalists and the proletariat. The contradictions between the two will always exist before entering a communist society. The so-called class issue refers to the problem of capitalists exploiting workers. Before the higher-level alien civilization enters a communist society, what will be the form of social production? We don't know for now, but if there is a large amount of production, workers must be used. With the development of technology, robots are replacing ordinary workers in more and more fields, and social conflicts need to be resolved urgently. Once this problem is solved, other problems will not be difficult to solve because all problems stem from exploitation. If it is not capitalists exploiting workers, it is the Pope exploiting believers, foreigners exploiting domestic capital, and so on.
Being able to eliminate class not only means that the alien civilization has entered a higher stage, but also proves that they have enough energy to regulate other problems. They can use this time to enter a communist society as soon as possible and achieve a highly developed civilization. This is also a promotion for themselves. From this perspective, there seems to be no reason to invade and exploit other civilizations. Otherwise, the meaning of the progress of a higher-level civilization will be lost.
Seventh, the problem of wealth disparity.
We all know that socialism has a problem of common prosperity. After entering a higher-level civilization, aliens will no longer have the problem of wealth disparity because there are no classes and naturally no currency. Phenomena that measure wealth disparity with currency or wealth will not exist. Everyone is equal, so the theoretical understanding of human rights by aliens will be enriched. By invading and eliminating alien races, because they develop slowly, it is obviously not in line with the ideals of this advanced civilization. Therefore, there is no need to worry about alien invasion. The only thing that needs to be solved is that humans bring their own conflicts and struggles to all aliens who visit Earth, which will cause conflicts and struggles caused by humans themselves.
Eighth, the issue of energy.
The issue of energy is ultimately the most important issue. Energy is an important guarantee for the production of materials. If aliens are civilized enough, they will have enough technology to ensure that they have inexhaustible energy, such as nuclear energy. At the same time, if they feel that renewable energy cannot sufficiently guarantee the long-term operation of their communist society, they can completely conduct scientific research and colonization externally. However, this behavior will mostly be directed towards planets with abundant resources. As I mentioned before, the energy on Earth is mostly exhausted by humans. Except for nuclear energy, there is no other future energy source. Or some niche energy sources, such as using hydrogen energy through water electrolysis. However, I think that if aliens can travel through high-tech in their neighboring star systems or jump between planets, their spacecraft itself requires huge energy. It would be a waste to drive a huge force to attack humans. If they use high technology, they must have discovered a way to maximize energy utilization. Since they have this method, why bother to deal with humans?
...
If aliens consider themselves to be a higher civilization, then they must go through all of this in order to achieve a unified and consistent social and political moral concept, such as entering a communist society.
At this moment, the aliens have long had a high level of understanding of the term civilization and will never launch aggression against others, especially against undeveloped civilizations, because they are highly developed, self-sufficient in energy, and have no need to do so.
Imagine, if a higher-level civilization wants to destroy a lower-level civilization that has not yet developed to its level, then this so-called higher-level civilization itself should be destroyed, not to mention that if there is such a civilization in the universe, there must be another civilization of the same level or even higher level. When these highest-level civilizations see middle and high-level civilizations developing towards lower-level civilizations, if they just stand by, it is obviously abnormal. At the same time, when these so-called higher-level civilizations invade lower-level civilizations, will they think that there will be another higher-level civilization watching them?
