Why is it said that after one billion years, the earth will change back to 4 billion years ago?

Whether the earth will return to what it was 4 billion years ago in one billion years depends on the direction of the development of human civilization, and whether the future will lead to confrontation or integration. If it is confrontation, then Human civilization will eventually destroy itself. If it is integration, we may be able to find a new path.

What did the earth look like 4 billion years ago? At that time, it was still desolate. To put it simply, there was no breath of life. Within the first 5 million years of the earth’s birth, the surface of the earth was like Like a fireball, it has just been born and has not really cooled down. The sun was born almost 5 billion years ago, and the earth took on the sound almost 4.6 billion years ago. After that, it went through a cooling-off period and experienced some changes in chemistry and physics. With a meager amount of carbon dioxide and nitrogen in the air, there was slowly a basic space for biological development.

If human beings move towards cooperation in the future, human civilization may break through the constraints of the current earth, because the most important thing for human beings to develop so far is that human beings have smart brains, which is very scary. of. Our individual strength is far behind that of lions and cheetahs, but when it comes to the power of unity and the smart brain of humans, no creature known on earth can compare with humans. If we can gather together, the entire planet With the resources and power, we can completely break through the constraints of the existing earth system and move towards a new planet.

If mankind heads towards conflict in the future, the consequences will be very serious, because not to mention the development of science and technology in the next few decades and hundreds of years, even now, in addition to the five permanent members, some countries have already With nuclear weapons, if each other carries out devastating attacks, you hit me once and I hit you once, and both sides carry out nuclear strikes, the earth will eventually become a desert. Although the nuclear warheads owned by various countries in the world are now announced The size is limited, and it seems that it cannot reach such a high level, but this is only announced. The hidden armed forces do not know how many nuclear weapons there are. Those weapons were 60 years ago.

If human beings can cooperate and exert collective wisdom together, our civilization can move to a higher level. But if human beings go into conflict to fight against atomic bombs, which were weapons from 60 years ago. , haven’t there been any developments in weapons in 60 years? This is not necessarily true. The final result is that each other's civilizations will destroy the earth. After a long recovery period, it will return to the way it was billions of years ago. There is no conflict among any creatures. After a long recovery period, a new generation of creatures gradually emerges. As for whether they are intelligent, we do not know.
