Are there aliens?

Yes, aliens outside the earth and earthlings may become aliens on other planets.

Because the universe is so big, life can't exist only on the earth. There must be life on other planets, but we haven't found it yet. People on earth have landed on the moon, and then these astronauts have become aliens on the moon, so there are aliens in the universe.

What's more, there are people on other planets, because these people have become aliens on this planet.

No one can answer the question whether there are aliens outside the earth in the universe.

But what is certain is that there is no conclusive evidence that aliens have visited the earth so far.

It is common for some people to describe natural phenomena that cannot be explained by science today as UFOs.

And many times what they see is actually an artificial plane.

Others describe the ancient civilization of mankind as an alien civilization, and attribute everything that cannot be explained now to an alien masterpiece.

This is an insult to mankind itself! ! !

Actually, people's creativity is very strong. What we can't do now doesn't mean that ancient people can't do it.

Don't call everything an alien.

UFO refers to unidentified flying objects, generally referring to all non-artificial flying objects.

There must be UFOs, and there are many things that humans can't explain, but it is not known whether they are related to aliens.
