Are there really aliens in the world? Why do some people say they have seen aliens and even said they were abducted by them?

My answer is yes: Aliens in the narrow sense refer to highly intelligent life forms originating from stars other than the Earth. Aliens in the broad sense refer to highly intelligent life forms originating from other stars, including the arrival of Earthlings. Become an alien from other planets.

About aliens: 1. It is possible for both aliens outside the earth and earthlings to become aliens on other stars. Because the universe is so big, it is impossible for life to exist only on the earth. There must be others. There is life on the planet, but we haven't discovered it yet. Earthlings have already landed on the moon, and by then these astronauts would have become aliens on the moon, so there are aliens in the universe. 2 , what is certain is that there will be when humans land on other stars, because at this time these people have become aliens on this planet. And as for the question of whether there are aliens outside the earth in the universe, no one can tell yet. Answer. 3. But what is certain is that so far there is no conclusive evidence that aliens have ever visited the Earth. It is common for some people to describe natural phenomena that cannot be explained by current science as UFOs. There are things. And many times what they see are actually artificial aircraft. Some people describe ancient human civilizations as alien civilizations, and attribute things that cannot be explained now to the masterpieces of aliens. This is a disservice to human beings themselves. Insult!!! In fact, human creativity is very strong. What we can't do now doesn't mean that ancient humans couldn't do it. Don't just call them aliens.
