Why do scientists say that Earth could be a zoo of aliens, and what evidence do they have?

There is no evidence, this is just a speculation by scientists. Scientists have so far not discovered any civilization of aliens, which comes from a fear of the unknown. So they speculate that our Earth may be an alien zoo, which has no scientific basis, just a simple speculation.

Because until now, human beings have only been able to walk around the edge of the earth, and now the farthest place to reach the earth is still the moon. The farthest human spacecraft go is the edge of the solar system. There are also many unknown regions that are unknown to humans. Humanity is also confined to this.

This theory was first put forward by John Bauer, because mankind at that time, and of course now, has been searching for aliens and extraterrestrial civilizations to no avail, so such a bold idea was proposed.

Humanity has been living on Earth since its inception. Until now, mankind has not found another planet suitable for human habitation. Although it is possible that this is because human science and technology are not developed enough, and they have not explored the universe enough and not thoroughly enough.

We often say that we want to find aliens and know about the species in the universe that are as intelligent as we are. But so far, there are a lot of rumors of aliens. No real person has yet been able to come up with ironclad evidence for the existence of aliens.

Today, I'll take you to find out!

Because no extraterrestrials have been discovered until now, human scientists have various conjectures and theories about extraterrestrial civilizations. Some people say that maybe the species on other planets are the same as humans, and the technology is not so developed, and it happens to be far away, so it can't be discovered. There are also those who say that there are no aliens in the universe at all, and that humans are the only high-IQ creatures in the universe.

These statements are all arbitrary. But now there is a terrible saying, and that is the "zoo theory".

The "zoo theory" is that humans are actually in captivity by alien creatures with higher IQs and more advanced technology. And the earth is a cage in captivity, or the solar system is a cage in captivity. No matter how advanced human technology is, it is difficult for human beings to fly out of the solar system.

If we say something bigger, there's a good chance that the entire galaxy is a cage. With the current human technology, it is impossible to fly out of the galaxy, even if it develops for another 10,000 years.

If the above statement is true, then what is the purpose of aliens keeping humans in captivity? Humanity is now studying itself in the hope of unlocking the mysteries.

Extraterrestrial beings may want to understand themselves by understanding human beings, or how human technology is developing in some unique environments. This kind of understanding may be a good thing for the advanced civilization of the alien world.

Perhaps the alien creatures kept humans in captivity for harvesting. Just like we humans keep cattle and sheep in captivity, just for the sake of simple harvesting. It's just that in the eyes of extraterrestrial beings, the cycle of captive humans is very long.

Humans are not in captivity, the earth is not a zoo, and scientists are not yet able to find evidence because we have limited technology for the exploration of outer space.

I don't think so, it's not in captivity, it's not a zoo, scientists can't find evidence, it's just a conjecture.

For the time being, scientists have not been able to find evidence, this is just a conjecture, and there is no scientific basis.

Do aliens exist? Scientists put forward the zoo hypothesis, and humans are "animals" in captivity?

In the vast and infinite universe, aliens and advanced life definitely exist. But at the moment there are no real signs of aliens. Some of the alien news reported on ** is false news that cannot be verified.

As for the mystery of the universe and the mystery of extraterrestrial life, human beings need to continue to explore, research and discover in the future.

Yes, there is technology that will not make such a difficult time appear.
