Some people say that UFOs are alien flying machines, what do you think?

Most of them are unmanned intelligent aerial vehicles, and there are also intelligent synthetic biological vehicles. The purpose is to observe the development process of human intelligent civilization.

There is no proof of death, let it be nonsense. Harmless.

I suspect they are ocean people, and they can't be people outside of Earth.

The underground is the real alien fungus world, and there are also antimatter droplet shuttles on the bottom of the sea, which is a highly civilized technology hundreds of millions of years ago, why use it to find it in outer space.

It could be the undersea or the inner of the earth. They don't need oxygen to survive. So there is no danger to humans.

I have seen UFVs UF, that is in 1993, in Taiyuan City, Wuyi Road and Wuyi Road when Wuyi Primary School was built, not me, but many people, thousands of people. The next day, the UF incident was also reported in Taiyuan**. The duel seen is not an earthling's flying machine.

UFOs are a few years later with a time travel spaceship for high-tech earthlings.

From ancient times to the present, there have been many UFO incidents recorded and witnessed by people, and there are even some foreigners who claim to have been abducted by aliens. Some people also claim that there are aliens in Area 51 of the United States, saying that aliens are helping the United States develop high technology. Then from so many events, it seems that UFOs should exist.

We don't know exactly what happened.

I think there are aliens in the world, in the summer of 2016, when I was on the roof, I found a meteor-like thing in the northeast corner of the sky from the sky, his light was like an LED light, flashed four different lights, and it appeared for about three seconds, the time was too short, I didn't have time to take out the camera to take it down! I think it might be a UFO!

Humans are curious about the unknown, and I think the UFO is a secret organization organized by a certain country to cover it up.

I think it makes a lot of sense, just like we humans invented rockets to explore the universe.

Alien vehicles don't have to be UFOs, UFOs are UFOs, maybe something else.

UFOs, more than 80% have been explained. None of the explanations have been extraterrestrial spacecraft, there are discarded spacecraft parts, natural phenomena, and so on.

The term UFO is too broad, referring to all UFOs that human science cannot determine at present, as for what it is, or whether it is a vehicle used by alien species, this is also a very vague thing, I believe that there are "aliens" in the galaxy, but they patronize the earth, how did they come? Anyway, it's all still a mystery.

The flying saucer should be an alien spaceship, because there are witnesses, for example, in the past, there were soldiers standing guard in the army who found that the devil was coming, and others didn't see the devil coming up, so they didn't believe it, and it was wrong not to believe it.

My neighbor might be an alien
