Desperate for a record of UFO appearances!!!!!

Aliens only exist theoretically.

UFOs certainly exist, but they are not the same as alien vehicles. It may be an earth-atmosphere phenomenon, a secret vehicle, a ** test, the combustion of residual fuel from a rocket engine, etc.

UFO.

UFO stands for Unidentified Flying Object, also known as Unidentified Flying Object (UFO) refers to an object of unknown origin, unknown space, unknown structure, and unknown nature, but also floating and flying in the air. Some believe that it is a spaceship from another planet, while others believe that UFOs are a natural phenomenon. Beginning in the 40s of the 20th century, saucer-shaped flying objects were discovered over the United States, then called "flying saucers", which was the beginning of contemporary interest in UFOs, and later people looked at UFO reports around the world, but no credible evidence has been found so far.

Many UFOs** have been identified by experts as **, and some are believed to be ball lightning, but there are always some discoveries that cannot be explained by existing scientific knowledge.

There is no conclusive evidence that aliens ever came to Earth.

I saw a painting in a certain **.

The portrait is a portrait.

Behind the man there was something like a saucer flying in the sky!!

My classmate said he had seen it, grey.

Beijing has the latest one searched online.

Human realization? The body temperature is 37 degrees, and the number of advances refers to.

The Rosville incident in the United States, the Duliba Stone Disc in China, and the Tunguska in the former Soviet Union.

Absolutely. There is life on Earth, why can't there be extraterrestrials!

And many scientists have also done experiments to try to kill bacteria on the earth, but they can't kill them completely. Without oxygen and water, some of the bacteria survived and began to mutate!

Yes, if you think about it, the earth is just a small grain of sand in the vast universe, and since there are people on the earth and Yinshan, there will also be aliens. If you dare to be interested in UFO video clips, I will introduce you to **, which includes a lot of UFO videos from all over the world.

Although scientists believe that even if there are aliens, it is impossible to fly to Earth because of the huge distance between the planets, they do not deny the possibility of intelligent life in outer space.

Whether extraterrestrial beings exist.

UFOs exist in mysterious ways, and tens of millions of earthlings claim to have seen UFOs. Are these "witnesses" fantasists or **? Or is there something between a lie and a truth?

Is the answer on a planet in space, or is it from humanity's cult of mystery?

The first boom in UFO research in the world began with the most famous "Arnold event" in the history of UFO research. UFO is an English abbreviation that means "unidentified flying object", also known as "flying saucer" or "UFO", which refers to a moving flying object or astronomical spectacle, which can be observed by the naked eye or monitored by radar, and is currently unexplained by humans. People who are interested in UFOs not only speculate that this is from a civilization that is more advanced than the earth, but also explain this phenomenon with the psychological hypothesis that the problem that modern humans may face.

UFOs are described as: moving or circling rapidly; Silent, erratic, or unusually roaring when moving; Shapes such as saucers, cigars, sphericals, rings or ovals have been counted in more than 100 different forms.
