Is the Earth the only civilization in the galaxy and even the universe?

I think this probability is still very high, at least 90%, because so far no other planet has been found to have human conditions on it.

This probability is still very high, the probability is at least 99%, and it is unlikely that there will be life on other planets.

Scientists have never stopped exploring the universe, and they always have beenFind other intelligent civilizationsHowever, there are also many people who believe that the Earth may be the only intelligent civilization in the entire galaxy or the universe. But this thinking is probably because we still haven't found other intelligent civilizations, soOnly then do people want to believe itUntil now, only the earth has an intelligent civilization.

Scientists have been working since a long time agoExplore the universeThere are also attempts to find other intelligent civilizations, but perhaps because our current technology is still thereNot to that pointSo far, we still haven't found itOther intelligent civilizations, but that doesn't mean it's just the earthOnly then can there be wisdom and civilization。Because there is so much in the universe, but the universe that we have now that we can reach is still very limited, and it can be touchedThings are also limited, so it could just be usThe existence of an intelligent civilization has not yet been found

In fact, there are many people who also wish that only the earth has itThe existence of intelligent civilization, because once there are other intelligent civilizations, it means that there may be a potential threat, but thisScientifically, certainly a big step forward. And the culture that other intelligent civilizations have brought to us may also be unexpected to us, butIn terms of probabilityWisdom we are likely to exist becauseThe universe has been bornThere are 13.8 billion years. In the midst of this, the whole universeHow many civilizations have been born, and how many galaxies were born, in fact, weThe understanding of the universe is not thorough enough

And for so long, the talk of aliensIt never stoppedIf aliens really exist, it means that there are other intelligent civilizations. And scientists are exploring the universeExplore other intelligent civilizationsexists because we need to goA deeper directionto develop.

Earth is the only intelligent civilization in the entire galaxy or the entire universe. Because people are very curious about space and the universe now, but no other intelligent civilization has been discovered so far, so the earth must be the only intelligent civilization in the whole galaxy. Although the universe is very large, there are very few civilizations in it, and the earth is unique.

Yes. Probably not, now human beings have only studied a corner of the universe, maybe there is intelligence in the universe that human beings have not touched, and human beings may discover other civilizations in the future.

At present, the earth is indeed the only intelligent civilization in the universe, but I believe that in the near future, mankind will find other intelligent civilizations.

The peculiarity of the Earth is manifested in the fact that it is the only planet where life exists. Humans, on the other hand, are very intelligent creatures. This also makes the earth one of the most unique.

No, I think there must be other advanced civilizations in the galaxy, but we haven't discovered it yet.

It's just that it hasn't been discovered yet With the current technology, many details are not observed, and the farthest man-made aircraft hail attack has only flown to the vicinity of Pluto It has not yet left the solar system And the silver destruction filial piety system is similar to the solar system There are countless star coefficients, among which there are many terrestrial planets, although the living environment required by living beings is very harsh, but who can guarantee that there is absolutely no place with the same atmosphere, water, and temperature as the earth Hasn't NASA just discovered a terrestrial star 600 light-years away from Earth, with an environment very similar to Earth, and it is very likely that life exists?

So this particular planet is definitely not an isolated case

In the past, I thought that there was only one sun in the world, but now I have gradually understood that the sun is just a star, and most of the stars in the sky are one sun, and they are just too far away, so it is too stupid for people to say that aliens do not exist if they can't see them now

Not necessarily. With the current level of human science and technology, there is still very little exploration of the universe, and it is possible that there are other life forms in the universe.
