UFOs have really appeared on Earth.

Yes, it is possible for aliens other than Earth or 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.

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.

I'll answer this myself. I'm a UFO enthusiast.

I think there is, because now I can see many planets that match the earth's environment, situation, and age with ultra-far-distance space telescopes. Scientists have calculated that there are more than 10 billion planets similar to the Earth in the outer galaxy, and it is very likely that there will be creatures similar to humans on those planets, and the technology may be far superior to that of the Earth.

On these planets, if they master warp space, wormholes, and faster-than-light technology, they will most likely be able to build what we call flying saucers.

So I think there is.

However, it is difficult to say for sure in the absence of conclusive evidence.

Humanity is searching.

Maybe aliens from outer space are looking for us too.

Do aliens really exist in the world?

Inventory of the ancient Chinese's records of UFO incidents!

Ghosts are the souls of the deceased who reappear in the world in their premortal form. Ghosts usually do not have a fixed form, and are generally invisible to the naked eye, and are only visible to certain people, such as relatives of the deceased, enemies, or people with yin and yang eyes.

Of course, there is, the history of human civilization is only a few thousand years, compared with the billions of years of the earth, such a large universe, we still don't know a lot, it is impossible for only our human civilization to exist, but we have not yet discovered it, and the most likely existence of extraterrestrial life in the solar system is at present.

Mars Jupiter's 2nd moon.

Not on Earth.

The space of the universe is infinite.

There are also many planets.

We have humans on our planet.

Creatures from other planets are called UFOs to us

That's for sure.

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