Why did the universe produce human beings, and why did there exist a universe? Why do humans appear?

If you want to look at this question from two aspects. One is a purely scientific perspective, and the other is a philosophical perspective.

Scientifically speaking: first of all, human beings are also matter, composed of a variety of different cosmic components, of course, this composition requires certain conditions, such as the necessary temperature, water, air, and the environment that does not change much, theoretically, as long as there is a similar environment to the earth, can give birth to life, scientists in the simulation of the earth is still in the wilderness period, electric shock of water-rich land, there are some Anji acids and the like, therefore, we can conclude, Life is the product of chemical reactions in lightning and lightning, and as for man, it is all due to evolution. Therefore, the phenomenon of life is not an accidental phenomenon, but an inevitable one.

It's just that there are too few planets in the universe like Earth that are the right size, the same distance from Huan Xing, and rich in atmosphere and water, so we have not been able to find extraterrestrial life (I heard on the Internet that the Mars probe in the United States found frozen bodies of life older than single-celled organisms in the frozen soil below the surface of Mars. But it's not an official report, and we don't care if it's true or not) But it's also good that if life on Mars evolves with us, I'm afraid it would have been dark long ago.

Let's talk about it philosophically, why does the universe produce man, if the universe does not produce man, then there is no such problem, because only our existence has the basic conditions to discuss this issue, so it should be said that we are conditions, if we don't even have conditions, then the universe itself has no meaning, and no one will discuss this issue.

Survival of the fittest in natural selection. In fact, the universe has produced many things, and humans are just one of the many species that have adapted and evolved.

It should be precisely why the earth produces humans.

Because the earth has water and an atmosphere suitable for human habitation.

According to the principle of human existence, the universe as you see it is like this, the universe has multiple histories, and we are only in one of them.

People are produced because if you weren't, you wouldn't be asking the question.

lz your own question has been your own, because the universe is like this so we are here, because you are human, so you have to ask this question.

If you analyze it from a scientific point of view, you will find a lot of amazing things that you can't study.

Thank God or Nuwa.

You have this kind of problem with"Why are you called human?"It's the same. Please, when I saw LZ, I suddenly had a sense of superiority in IQ.

Natural selection of things and survival of the fittest.

The creation of the universe was a fortuitous event, and why it was born may be that God created it. In the process of expanding the universe, water matter appeared, and life on earth was born, and human beings gradually developed into civilization. Humans are very lucky.
