Are we really aliens?

First of all, for civilizations on other planets, we humans are aliens. Because we don't live on their planet, of course we are aliens on other planets.

Secondly, did the earthlings immigrate to the earth from other aliens? It should be said that this possibility exists. Because the emergence of life on earth is a difficult thing to explain. Modern science believes that the combination of carbon atoms and other organic molecules in a specific environment leads to the emergence of life. This theory is really just a guess. Because human beings have not been able to reproduce life in lifeless places according to this theory. For human beings themselves, its appearance is also difficult to be explained by evolution. In fact, evolution has been challenged more and more in recent years. One of the main challenges is that genetic research shows that human genes contain some genes of lower organisms such as fungi, while those of apes and other animals do not. So it is hard to say that human beings evolved step by step from those lower creatures.

In fact, the theory of extraterrestrial origin of life on earth is becoming more popular now. Because scientists have found that comets and some meteorites can indeed bring water and other organic molecules to the earth. In addition, some foreign scientists have found that there are a large number of fine particles floating near the edge of the earth's atmosphere and outer space, and these particles contain mysterious liquids. So they concluded that these particles were the seeds of life.

In short, it is obvious that aliens created human beings, or that human beings are descendants of alien immigrants.
