The vastness of the universe is beyond human imagination. But in fact, there may really be a planet in the universe that is more developed than our earth civilization. It's just that this planet is too far away from us, and humans can't fly that far, so humans can only keep guessing. Of course, scientists have also sent many probes into space to see if there are other planets in the universe through telescopes. Even if we can't, we can have a look.
Later, after people's understanding of the universe became more and more in-depth, they could not help but sigh, has human beings been arranged to survive on the earth? If this possibility really exists, it means that human life and death are just the objects being played with, and human beings are deliberately arranged on the earth by alien civilizations. Human life is an experiment. If so, I believe many people will destroy the three views.
In fact, isn't human being observing and experimenting with other creatures? There are many creatures on the earth, which are used by humans for experimental observation. Such as zoos and botanical gardens. Now many people want to see animals. If they want to see animals, they will go to the zoo. Animals in zoos are actually objects of observation and experiment. So is it possible for humans to be observed by other alien civilizations?
Of course, this conjecture is just a trick or conspiracy theory of primary school students. So far, mankind has not found any kind of alien civilization interacting with us. Even if there is a civilization in the universe that constantly observes our lives, we don't need to be afraid. After all, we humans are alive and well now, and nothing has happened.
