The earth is a living planet, the most primitive simple life was born in the ocean for 4 billion years. After a long period of evolution, life has become richer and more complex. More than 500 million years ago, some organisms in the ocean moved to land in order to survive, and the evolution of marine organisms to terrestrial organisms began.
After the birth of terrestrial organisms, the rate of evolutionary evolution is astonishing. Although the earth has experienced five mass extinctions in more than 500 million years, the evolution of terrestrial organisms is getting faster and faster. Until millions of years ago, human beings were born, and human beings follow the evolutionary path differently from other creatures. Animals follow the path of power, while humans follow the path of wisdom.
With the help of wisdom, humans with weak physical strength began to grow stronger and became the hegemon of the earth, and formed human civilization more than 5,000 years ago. The formation of civilization has allowed humans to develop faster and embarked on the path of scientific development hundreds of years ago.
With the help of science, human civilization finally ushered in a glorious moment. Soon we walked out of the earth and began to explore the universe. Humans have not existed for a long time, far from being compared with the dinosaurs that dominated the earth for 160 million years 65 million years ago. But because human beings are intelligent beings, we can think and become enlightened, and continue to explore the mysteries of this world through thinking and enlightenment.
Although mankind’s true understanding of the world has been since entering the age of technology, the exploration and thinking of this world has been tens of thousands of years. In ancient times, human beings had already thought about the starry sky, the nature of the world, and human beings themselves, but at that time they lacked scientific guidance, and given many puzzles and puzzles the attributes of gods.
Among the many incomprehensible puzzles, there is one puzzle that has kept the ancients and modern scientists thinking deeply, and that is, what is the meaning of human existence? In fact, the ancients were not as persistent as modern scientists for this confusion. Many people in ancient times believed in the existence of gods. In myths and legends, human beings were created by gods, so the meaning of human existence is not much worth thinking about.
But when mankind entered the age of science, we all knew that there was no god in this world, and that the mysterious phenomena that ancient humans were puzzled by can all be answered by science. We understand that humans were not created by God, but an evolutionary evolution of life. It is the primitive simple life that gradually evolved into humans.
Many people may say that researching and exploring the meaning of human existence is a completely boring topic. Is this really true? Of course not. The more advanced technology is, the more we think about the meaning of human existence. Especially when human beings have gone out of the earth to explore extraterrestrial life and extraterrestrial civilization without any progress.
When human beings walk out of the earth and see the vast universe, people will think: Does alien civilization exist? The more you know about the vastness of the universe, the more you will feel that the probability of existence of alien civilization is basically 100%. In addition, from the time of 13.8 billion years in the universe, we can also think that if human beings can exist, then alien civilization should also exist, and at different times of the universe, there may be a large number of life planets and a lot of wisdom. Civilization appears.
If this is the case, then it should not be surprising that the universe has an intelligent civilization that is 100 million years more advanced than human civilization, a billion years or even longer. Once a smart civilization enters the age of science and technology, it will develop very fast. It only took more than 100 years for mankind to get out of the earth. Then a civilization that developed 100 million years, one billion years earlier than mankind, it is conceivable that, How powerful they will be.
Such a powerful civilization should have long ago possessed the ability to sail across the stars, and the universe may be just their back garden. If so, then the universe should be very lively, the earth should have already been patronized by many advanced civilizations, and we should have been able to come into contact with alien civilizations.
But the reality is not the case. The universe we see is very lonely, and until now no extraterrestrial life or civilization has been discovered. In theory, the universe should be very lively and intelligent civilizations are everywhere, but the reality is that we cannot see an alien civilization. Where have they all gone?
As for the fact that human beings have not discovered an alien civilization, scientists have given many speculations, such as the theory of the universe laboratory and the theory of the virtual universe. These theories sound reasonable, but in addition to these speculations, we have to think about another possibility, and that is that the entire universe has only one life planet, the earth, and only humans, an intelligent civilization.
If the above speculation becomes a fact, then we have to think, what is the meaning of human existence? If the number of intelligent civilizations in this universe is very common, and human beings are not the only one, then there is no point in discussing the meaning of human existence.
But once the future proves that human beings are the only intelligent civilization in the universe, then the meaning of human existence may far exceed our imagination. So what is the mystery behind this meaning? Let’s first look at what is the meaning of human existence to the earth? You must know that there is only one intelligent civilization on the earth, and the emergence of mankind is of great significance to the earth.
We all know that this universe, whether it is a star or a planet, basically cannot last forever. After the star runs out of fuel, it will enter the end of the explosion, and finally evolve into a white dwarf star, a neutron star or a black hole. If the star is destroyed, the planets near it will naturally be difficult to escape, and even the entire galaxy will die.
The sun is also a star, and its life span is about 10 billion years. When the sun’s life comes to an end, the earth and even the entire solar system may be destroyed. Even if the solar system can be preserved, the earth, as a habitable zone, will be swallowed by its orbit and disappear into the universe during the large expansion of the sun.
This is a natural destiny of the earth. Without the emergence of human beings, the earth would be able to exist for another 5 billion years at most. However, the emergence of human beings may change the fate of the earth. We can go to the starry sky through science and technology, so the power of science and technology may take the earth away from the solar system to other galaxies, so human beings can bring their parent stars into the interstellar together. It can be saved for a longer period of time, completely changing its destiny.
In the same way, the universe is unlikely to be eternal, and its expansion may not last forever. One day, the universe will also come to an end. How long will this time take? At present, we don’t know yet. When the life span of the universe is over, then the entire universe will disappear or return to zero again and evolve again.
This is the destiny of the universe under normal circumstances, but the birth of mankind may change the destiny of the universe in the future. The reason is simple. Humans have mastered the great power of science. Science is the supreme law above the universe. Through science, we can understand everything in the universe and master everything in the universe. Naturally, we will also know what ultimate destiny the universe will face in the future.
We have the ultimate power of science, so we can use it to adjust the operation of the universe. In this way, the life span of the universe can be greatly increased, and even the destiny of destruction can be completely transcended by the universe, and eternity can be truly realized. If human beings are the only one in the universe, then the meaning of our existence may be to change the destiny of the universe in the future.
