Is there really an alien, and if so, say why, and if not, say why

Yes. The Sun is a star, and there are 2000 to 400 billion stars in the universe, and that's probably a conservative number, because scientists are always making new discoveries.

Every star is surrounded by planets, just like our Earth is orbiting the sun, so many of them, can you believe that there are no aliens? In the universe, our existence is negligible.

There are quite a few Earth-like planets that have been discovered, the most recent of which is 20 light-years away.

We can see but we can't get there.

And the one on the first floor is really depressing. Answer science with superstition.

1. Aliens: Refers to people who live on planets other than the earth and should be human, and should at least have the important characteristics of human beings, that is, they have the ability to reproduce, survive, think and communicate, regardless of their form; Otherwise it can only be an alien creature.

2. Earth lunar explorers, when they reach the moon, they are aliens to the moon!

The existence of aliens has always bothered us, since ancient times aliens are a mysterious existence, human beings are afraid of them but want to explore, there is news that the existence of aliens has finally been confirmed, and it is nonsense to think about it. Recently, all kinds of things about aliens have happened, and in the end, they have not been confirmed, and it is believed that the aliens have not yet been confirmed.

There are ** reports of aliens and the wreckage of alien spacecraft found in Antarctica, and the personnel of the scientific expedition have found traces of spacecraft passing in Antarctica many times, and many people think that there are aliens in Antarctica, and they exist under the Antarctic ice. It follows from this that there is a high probability of aliens in the polar regions.

Studies have shown that human civilization is likely to come from the ice-covered Antarctic, and that aliens are on the Antarctic continent. This news caused quite a stir after it came out, and some people even believed that the Chinese were the ancestors of aliens. It is known that in 1991 there were UFOs over Mexico, and these UFOs were believed by many to be alien spacecraft.

In addition, the cancellation of China's lunar landing program is also reported to be influenced by aliens. Since the U.S. moon landing in 1969, the Chinese have been studying the moon landing, but the upcoming moon landing program has been canceled. Some people say that China's cancellation of the moon landing is due to the threat of aliens, but now it seems that China's moon landing program has nothing to do with aliens at all, and it is still uncertain whether aliens exist or not.

Although human beings have always hoped for the existence of aliens, or have been studying whether there are aliens, so far human beings have not made contact with aliens, nor have they obtained any valuable and meaningful clues. Stephen Hawking once expressed the hope that human beings will not get in touch with aliens in the future, because we don't know whether the other party is friend or foe, but before that, there is a premise, aliens really exist.

Why haven't we found the "aliens" until now? Scientists have finally told the truth!

Many people say that there are alien corpses in the United States and Russia, and these people think that ** is a conspiracy theorist and thinks that ** will deceive them again. If aliens really come to Earth, the Earth will be finished long ago.

I also said that I have seen immortals, and many people say that it does not mean that it is true, after all, the three of them become tigers.

Because a lot of people are lying, they haven't seen aliens at all.

I am Chinese, and I have always had a question about how many Chinese have seen aliens like me, and this is what they look like
