Is there really an alien in the universe?

Yes, it's possible for extraterrestrial aliens outside of Earth or for earthlings to become aliens on other stars. Because the universe is so big, it is impossible for there to be life on only the earth, there must be life on other planets, but we have not yet discovered it. And the earthlings have already landed on the moon, and at that time these astronauts have become aliens on the moon, so there are aliens in the universe.

It is also certain that there were humans when they landed on other stars, because at this time these people became aliens on this star. And the question of whether there are aliens outside the earth in the universe is still unanswered. But what is certain is that there is no conclusive evidence that aliens have ever visited Earth.

It is not uncommon for some people to refer to natural phenomena that cannot be explained by science today as extraterrestrial visits (UFOs). And a lot of the time what they see is actually an artificial aerial vehicle. There are also some people who say that the ancient civilization of mankind is an alien civilization, and attribute everything that cannot be explained now to the masterpiece of aliens, which is an insult to mankind itself!

In fact, human creativity is very strong, and what we can't do now doesn't mean that ancient humans can't do it. Don't say anything is alien. UFOs, on the other hand, refer to unidentified flying objects, which refer to all non-man-made flying objects.

UFOs must be there, and there are many things that humans can't explain. But whether it is related to aliens is unknown.

The universe is so big, it should exist, but we haven't discovered it yet.

Yes, the universe is big, anything is possible.

Are there aliens, according to what we ordinary people say now, there must be aliens in this universe, but why have we been probing for so long and still have no clues? Some people say it's because aliens are hiding them, so we can't find out.

Aliens must exist, and we can't know about them directly, we can only wait for the continuous progress of our technology. Only with the continuous progress of our technology can we be qualified to explore aliens, and at that time we will understand aliens.

This requires a lot of research probing. It is not possible with the current level of science and technology.

There should be no aliens, and life on Earth is still very peculiar.

No. There are many planets in the universe, and although some rumors say that other planets may have signs of life, there is no evidence of the existence of aliens.

I think there is. Because the universe is huge, the earth is just one of the planets. There may be creatures on other planets that we don't know about.

Although the universe is large, after so many years of research by scientists, no alien footprints have been found, so I don't think there are aliens at all.

Possibly, after all, in addition to the Earth, there are some secrets in the universe that have not been discovered by humans.

There may be aliens, but after so many years of searching, there is still no news of them, I think there must be none, in fact, there are many hundreds of millions of light years away, and it is impossible for us to meet.

Personally, I think that there are no aliens, and if there are aliens, they will definitely explore our earth, but with our current scientific development, we have not found these conditions, so there should be none.

Hearing is false, seeing is believing, and according to the current understanding of human beings, aliens definitely do not exist. If it existed, we would have communicated and communicated with him a long time ago.
