If only life exists on Earth, what is the significance of the existence of the universe after the de

For the universe, the earth we live on is just a very small existence, so to tell everyone, the earth we live in belongs to the Milky Way, and the Milky Way is only a medium galaxy in the universeThere are at least billions of such galaxies, so the earth is normal, and the special thing is that only life has been found on the earth, and people will wonder if there is only life on the earth, what is the meaning of the existence of the universe after the destruction of the earth? The universe itself is of great significance, with countless opportunities for development, and it is not as simple as we think.

First of all, we humans live well on the earth, but when we go to the universe, we humans are just like this, and the resources on the earth are not enough to support human beings for too long, which requires the search for new resources, so there is a second planet, the simple understanding is to find a second planet suitable for human habitation, which takes a lot of time to explore, and there are currently some goals, such as Mars, whether it is the distribution of the atmosphere or the distribution of time are very similar to the earth, But water resources are not found.

So in this way, even if the earth is the only planet with life at present, if the earth perishes, it will have no impact on the universe, after all, there are so many planets in the universe, each planet has its own lifespan, and the collision and death of planets and the like are also common occurrences, these are commonplace, we should not regard the earth we live in as the most special existence in the universe, but the existence of living beings.

There must be some planets in the universe that can be used as second planets, but the distance is too far for us to explore, but even if the earth perishes in the future, there will still be the birth of life, and it will be the next earth, which is a meaning of the universe, and there are countless development spaces, these are things we don't know.

I think that after the destruction of the earth, the meaning of the existence of the universe is to continue to create conditions for the next "earth" to be formed in the long course of history, and then the human beings of the new earth will start to study the universe again and again.

The existence of the universe must have its significance, and human beings are just a passing passenger on the long road of the universe. Life doesn't just exist on Earth. There is life on other planets as well.

It is not because of the universe that there is an earth, but because there is a universe that there is an earth, and even if there is no earth, other intelligent beings may be born.

Whether there is life on planets other than Earth in the universe is yes, but it has not yet been discovered. Theoretically, the universe is infinite. The Earth is just a planet in the solar system, and the solar system is just a tiny part of the Milky Way.

There are about 150 billion stars in the entire Milky Way, and there are quite a few planetary systems like the solar system, among which planets similar to the Earth must exist. It can be guessed that the Earth is by no means the only celestial body with life. However, humanity has yet to find another planet with life.

Related information: The basis for the birth of life is organic matter, and organic matter must be composed of at least oxygen, nitrogen, hydrogen, carbon and other elements. Then, there are certainly not a few planets in the universe that have these elements, as long as there are suitable conditions, these elements can be combined into organic matter, and then these organic matter is constantly evolving, and finally life is born.

Take the evolution of life on the earth as an example: the oxygen, nitrogen, hydrogen, carbon and other elements on the earth form proteins under the action of the sun's ultraviolet rays and thunderstorms; It is also a coincidence that the earth is at the right distance from the sun, so there is life. Life then evolves further due to the constraints of the environment.

Then after n billion years of evolution, humans were born. There are trillions of planets in the universe, so there must be a few in the universe to find a place with similar geographical conditions to the earth. Therefore, we cannot say that there are no life forms other than the earth.

So far, the only planet discovered by mankind is that there is life on Earth.

However, recently the American Perseverance has discovered organic molecules on Mars, which is the basis for the existence of life, and the universe is so vast that it is not excluded that there is life in distant places that we cannot explore.

Maybe one day we'll dig up a Martian on Mars, and that's not impossible.

According to expert observations, there is a star galaxy 5 billion light-years away from Earth, very similar to the Sun, in which there may be signs of life, and even higher intelligent life may appear.

Is there or how many celestial bodies like Earth are there in the universe. The organic molecules on Earth do not fly from outside the sky, but they are possessed by themselves, and substances such as water and oxygen, which are necessary for the existence of life, are also abundant in the embryo of the Earth. What is important, then, is the external conditions that cause the evolution of these organic matter, that is, the light and heat conditions from the sun, which are the external conditions that enable the evolution of the earth's organic matter into living matter.

In other words, because the earth has the two conditions of organic matter and solar light and heat, it also has the necessary conditions for the existence of life. In this way, we just need to explore whether there are planets and star systems in the universe like the Earth-Sun. According to research, there are about 1% of stars of the same type as the Sun in the Milky Way, and at least 10% of them have planets, that is, 100 million stars like the Sun have planets.

So among these 100 million planets, are there any planets that are completely consistent with the internal and external conditions of the Earth? In fact, there are countless galaxies like the Milky Way in the entire universe. According to the theory of probability, we can think that there must be celestial bodies in the universe that are the same or similar to the earth in addition to the earth, that is, there must be living planets like the earth in the universe, but we have not discovered each other.

The vastness of the universe is certain.

It's not just life on Earth. In the solar system, only the planet Earth has life. In the Milky Way, there are four stars in a similar position to the solar system, all of which may have life.

There are at least one billion galaxy clusters similar to the Milky Way, so there may be four billion objects that have life. It's just that these celestial bodies are very far away from the Earth, and humans can't detect them for the time being.

What can be determined now is that there can be human beings on the earth.

I think there should be more than just life on Earth in the universe, because there are countless planets in the universe, and there should be planets similar to Earth, and life may be born on it.

Not only is there life on Earth, but there must also be life on other planets, but we don't know much about other planets, so we haven't discovered them. No matter what planet you are on, there are living creatures that may not be the same as humans, but the species are also very rich and diverse.

I don't think there's anything wrong with that; After all, so far, we have only found traces of life on Earth.
