Humans have not yet found extraterrestrial civilizations. For this reason, many people say it is difficult to understand: the universe is so big, just humans are on the earth? Is it possible? Actually, I don't think it's possible. However, so far, humans have not discovered alien creatures. Many people have made explanations for this: some believe that alien creatures are in high-dimensional space , and some believe that many planets actually have life, but they do not belong to carbon-based life . In fact, I personally have a bad judgment: that is, it is very likely that humans may be in the state of " Easter Island ".
1, Easter Island
From the perspective of world history, in human history, the main force in creating human civilization was actually in Eurasian continent : When the Eurasian continent created a brilliant civilization, the American continent was very primitive, and Tower Island and Easter Island even showed a state of regression in civilization. The reason for this phenomenon is very simple: civilizations in Eurasia can communicate with each other and make continuous progress. For example, Chinese papermaking was introduced from Arabia to Europe.
, while the indigenous peoples of the Americas, Australia and Pacific islands outside Eurasia have been in a relatively backward state for a long time. Before the Age of Discovery, Americans, Aboriginal Australians, and Aboriginal peoples in the Pacific Islands did not realize their backwardness. Among them, Easter Island is the most typical.
Easter Island is located in the South Pacific Ocean, geographically located, and is very far away from the surrounding continents. Under ancient navigation technology, it was difficult for Eurasia to spread civilization to this type of civilization.
Assuming that there were people in ancient Easter Island who planned to seek "overseas civilization", they would probably think: Will Easter Island residents be the only ethnic group in the world? Some residents of Easter Island may also build ships to find overseas civilizations. But the sea is vast, and both America and Australia are too far away from Easter Island. This means that for the "observable world" of Easter Island residents, Easter Island natives did not discover the existence of overseas civilizations.
And just as Easter Island residents were regressing in civilization, the civilization of Eurasia showed rapid development. Of course, the sailors from Eurasia also found the Americas and Australia after their maritime technology improved by leaps and bounds, and by chance, found Easter Island.
For the indigenous peoples of America, Australia, and Easter Island, the sailors from Europe are equivalent to aliens invading their world.
2. The crisis of earth civilization
Assuming that the entire universe really does not exist extraterrestrial civilization, on the contrary, extraterrestrial civilization does exist, and the earth is in the state of Easter Island, then this is the most dangerous.
Although for humans, the distance of 1 light year makes the earthlings feel extremely far away. The limitations of technical conditions mean that the earthlings cannot go to other planets for investigation - at least to this day, humans cannot determine what the situation of Proxima Centauri b, which is 4 light years away from the earth.
Moreover, for humans, the Earth version of can observe what the world looks like outside the universe , so far, humans have not made any breakthroughs.
However, assuming that the interstellar transportation technology of extraterrestrial civilizations is constantly developing and has the ability to easily reach the earth from outside the observable universe, then sooner or later, the earth is likely to be discovered by extraterrestrial civilizations. At this time, for the people on earth, they are likely to face a very unoptimistic situation.
Therefore, for the earth, the greatest danger is that humans are in the state of Easter Island residents without knowing it.
However, even so, this is a very helpless thing. After all, Easter Island residents also had their own helplessness back then. They don't want to fall behind subjectively.
