Does anyone doubt the rules of survival on the earth, why do people exist, and the truth of the univ

Did anyone give you the rules of survival? No, the earth does not exist for humans, it is a product of the evolution of nature. 4.5 billion years ago, the earth was born, there was no oxygen on the earth at all, some were sulfur dioxide, there was no life, there could be no green plants.

The climate on the surface of the earth is cruel and harsh, not even the ozone layer, the sun shines on the earth, the heat is hot, with the continuous collision of asteroids and the earth, the diameter of the earth is getting larger and larger, and it is more and more able to attract the surface gas, the surface temperature of the earth is slowly declining and the average is stable, which is suitable for the birth of life, the initial birth in the ocean water, the virus evolved into a single-celled microorganism, only with the algae that can photosynthesize, oxygen slowly appears. Life on land depends on oxygen. When the earth is suitable for the development of life, it is the rule of survival of the fittest, cruel and ruthless.

Man is also the life of carbohydrates, a higher life. Because human beings are intelligent and love to work, they have developed into the pinnacle of the animal kingdom and dominated the earth. Why do humans exist?

Why? If you don't work, fierce tigers, terrible poisonous snakes and other animals want to dominate the earth, and humans are their slaves. Now the animals are all [driven out] by humans, forming a point where they dare to be angry and dare not speak.

Why does it exist, you ask? You become a fool and become a slave to animals. Animals don't ask why they live, they are greedy.

We are just a moment in the process of life in the universe, not cruelty, human beings cannot survive outside the earth, so, you say cruelty. The universe is not cruel to you.

Sun, Earth, Moon.

Solar system. If you don't care for the earth, destroy the environment, engage in a nuclear war, the earth will soon be deserted, and the flood era will come to the earth, can you blame the cruelty of the universe?

The rules of survival are changing all the time. The only constant is survival of the fittest.

People turn over on their backs, people come and go, people are crowded, and people's hearts are unpredictable.

There is currently no conclusive scientific evidence that extraterrestrial life forms exist in the universe. However, scientists generally believe that there may be life on other planets or celestial bodies in the universe. This is a speculation based on several factors:

The vastness of the universe:There are tens of billions of galaxies in the universe, each galaxy has tens of billions of stars, and there may be many Earth-like planets in them. Such a large scale of the universe provides vast possibilities for the existence of other lifeforms.

Planetary diversity:Some of the discovered exoplanets (exoplanets) are located in habitable zones (areas where planets' orbits are so close to their stars that temperatures are suitable for life) that may have Earth-like conditions, such as suitable temperatures, water resources, and chemical composition.

Robustness of life:Life forms exist on Earth in extreme environments, such as deep-sea hydrothermal vents and polar glaciers. This suggests that life may have the ability to adapt to extreme conditions, which also increases the possibility of other life in the universe.

Despite the scientific community's curiosity and speculation about the existence of extraterrestrial life in the universe, there is still a lack of direct evidence to prove this. Future scientific research, exploration missions, and technological advances may contribute to this exciting question.

Is there or how many celestial bodies like Earth are there in the universe. The organic molecules on the 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. 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.

What, then, is the best way to connect with each other in the vast universe? In terms of human wisdom and technological level, the best way to eliminate it is electromagnetic wave communication. Radio telescopes currently in use can receive very faint signals from space, but unfortunately, there is no indication that these signals carry information from advanced intelligent beings.

Another way is to compile symbols that represent the characteristics of the earth into "passwords" to make "earth business cards" and use electromagnetic waves to emit them into outer space. If aliens are about as intelligent as humans, they have the opportunity to receive and decipher the content of our signals, and then they send them to Earth. But even electromagnetic waves emitted by the nearest star of exactly the same type as the Sun would reach the Earth.

Light-year. Suppose this star has planets, and there are highly intelligent life on the planets, and they receive signals and feedback information, and a round trip is enough.

Light-year. Therefore, it is almost impossible for humans to meet them.

Is there only one life in the universe that exists on Earth? The characteristics of living matter on earth are organic matter with hydrocarbons as the main body, oxygen as the exchange material for metabolism, and water as the basic substance for the formation of life. After these conditions are met, at the right temperature, organisms can be formed.

If life could be formed from other substances, it would certainly not be in environmental conditions like Earth. But as long as they are living beings, they must also exchange matter and energy to maintain life activities.

We live on Earth and have countless curiosities about it. When we were children, we felt that the world in front of us was already very vast and large, until we grew up and understood the universe. This vast universe is all-encompassing, and many planets are included in it, and Earth is only a small part of it.

How small is the earth in the universe? Some people say that if the universe were the Earth, then the Earth might be smaller than an atom. It's not that the earth is too small, it's that the universe is too big, and the universe is so big that human beings haven't fully explored it yet, and it's always being explored.

I've seen a ** in a NASA release about Voyager, in which the Voyager 1 deep space probe was filmed six billion kilometers away from the Earth, the Earth is just a small dot that is so faint that it is almost impossible to find, and its presence in the universe can be almost uncountable, negligible. <>

Although the Earth is many times larger than the Moon and larger than Mars, Mercury, and Venus, Neptune alone is 58 Earths, while Uranus is 65 Earths, Saturn is equivalent to 830 Earths, and Jupiter is equal to 1,300 Earths. The central point of all this, the sun, is the big brother of the big guy, the size of 1.3 million Earths. In front of the sun, the earth is already insignificant, let alone what kind of position the earth has in the universe!

However, this is only about the solar system. The universe consists of the solar system, the Milky Way, and a series of galaxies. What's more, the solar system is nothing more than a speck of dust in the neighboring interstellar space.

Our homeland, the whole of our existence, and the source of our life, Mother Earth, is a smaller existence than dust in front of the universe, and we ourselves are the dust in the dust, which is not seen in the universe at all. The universe is so big and mysterious, and its mysteries still need to be explored step by step.

Equivalent to a grain of sand, in the universe, the Milky Way is a very small existence, and the earth is even smaller.

It is very small, there are many stars in the Milky Way, maybe hundreds of billions of stars, and it is difficult for the Earth to find these planets even with a microscope.

Human beings are very small in the universe, the whole universe is outside the earth, and the whole galaxy is very vast, so big that you can't imagine that human beings are smaller than an ant in the universe.
