How many years do you think the recorded history of mankind is? Li Zhantian suddenly asked.

> Like: The history of the written record is only 3,000 years, right? Ling Feng was stunned for a moment when he heard this question, and then he pondered and said, "China may have had a definite written record since the Spring and Autumn Period and the Warring States Period, Qin and Han Dynasties, right?" ”

& Not very accurate. "Li Zhan Tiandao," the earliest writing of human beings should be about 5,000 years ago in the Sumerian language of the two river basins in southern Iraq, also known as the 'nail head' script, and the hieroglyphs of ancient Egypt at the same time, these two kinds of writing have long disappeared in the long river of history, the earliest writing in our country should be the oracle bone inscription of the Yin Shang period, about 3,500 years ago, these may be the earliest written history of human beings. ”

Hearing this, Ling Feng couldn't help but wonder: "What about the Xia Dynasty before Yin Shang?" When he was a student, Ling Feng was quite interested in history, not to mention that many of what Li Zhantian said were not in textbooks, so he listened to them with great interest.

& I finish, don't interject. "Li Zhantian is a scholar of heaven and man, a wide range of ancient and modern, and many of the books in the Wuwei Sect are the only books that have been handed down since ancient times, and he has read them all, so when it comes to the knowledge before the pre-Qin period, he will not think about it as a second person in the world. Li Zhantian continued: "The Xia Dynasty is only stored in archaeological excavations, and there is no actual written and historical record, and the history before the Xia Dynasty has no physical basis, and only by virtue of legends can we have a general understanding. Therefore, it is inaccurate to say that it is 5,000 years up and down, and the history of China can be counted from the Xia Dynasty at most, about 4,000 years ago. ”

Many of what Li Zhantian said were views that Ling Feng had never heard of, and they were very different from the history he was familiar with, but he had to admit that what the teacher said made some sense.

& Whether there are any remnants of Chinese civilization in the past, the archaeological community has been looking forward to finding physical evidence. As early as the 30s of the 20th century, Chinese and foreign archaeologists embarked on a journey to find the origin of Chinese civilization for 5,000 years, they searched for the symbols carved on the pottery of Yangshao culture in the Yellow River Basin, and the 'words' carved on the pottery of the Dawenkou culture, trying to prove that the origin of Chinese civilization can be as early as 5,000 or even 6,000 years ago, but they did not find convincing physical evidence. ”

According to the law of historical development and our common understanding, human science and technology should develop from low to high, right? Li Zhantian asked.

Ling Feng was wandering out of the world and didn't react for a while, and the teacher had asked him not to interject at will, so the "yes" in his mouth shrank back when he reached his mouth.

Li Zhantian scolded with a smile: "You lazy boy, what do you ask? ”

Ling Feng resignedly, "Didn't you want me to interject?" ”

Li Zhantian raised his hand to fight, Ling Feng jumped away with a smile, and said loudly: "Human science and technology must be moving forward, and it is naturally developing from low level to high level." But before the words came out, he felt that something was wrong, but what was inappropriate, he couldn't describe it specifically.

& Ancient Babylon, Ancient Egypt, Ancient India and China, Babylon has the famous Hanging Gardens, Egypt has the world-famous pyramids, and China has the Great Wall. Li Zhantian continued, "Let's not talk about the Great Wall, let's talk about the pyramids in Egypt, the earliest pyramids were built before 2500 BC, more than 400 years earlier than the Xia Dynasty, which has no written records. The largest pyramid is made up of 2.6 million pieces of stones weighing about 10 tons each, and there is no cement or other sticky material between the stones of the tower, which has been beaten by wind and rain for 4,500 years, and its gaps are still quite tight, and it is difficult to insert a sharp knife. It is estimated that Egypt must have had to be inhabited by 50 million people at the time of the construction of the pyramids, otherwise it would be difficult to sustain the food and labor required for the project. But in the third millennium B.C., the population of the world was only about 20 million. In addition, a large number of laborers must work on the fields to maintain long-lasting food. The long and narrow Nile basin does not seem to be sufficient to sustain the construction team. You must know that the construction team needs at least 100,000 people, and can the agricultural harvest in the Nile basin alone sustain the needs of the project?"

& Even with today's technology, it is impossible to completely replicate the pyramid. In the past, Egypt demolished a small pyramid to build a reservoir and rebuilt it in another place, but the builders from all over the world did not rebuild the pyramid. How did the ancient Egyptians build it more than 4,000 years ago? ”

The wonders of the pyramids, Ling Feng has also heard a little. The pyramids have a connection with astronomy and mathematics that is difficult for modern people to understand. The construction of the pyramid determines a system of weights and measures, and the length unit of the Great Pyramid is determined according to half the length of the Earth's rotating major axis, that is, the base of the Great Pyramid is ten percent of the length of half of the Earth's rotating major axis; The weight unit of the Great Pyramid is a combination of the above units of length and the density of the earth; The thermal unit of the Great Pyramid is the average temperature of the entire Earth's surface. In addition, the burial chamber in the Great Pyramid where the pharaoh's coffin is displayed is 2:5:8 and 3:4:5, which are the formulas of the coordinate triangles. In addition, the ruins of the Great Pyramid are located in the middle of the meridian, which seems to give a glimpse of why the builders of the Great Pyramid chose this unique rocky area in the desert as the site of the tower. It is said that there are many beautiful murals depicting alien spacecraft inside the pyramids, and some scientists have even pointed out that there are also alien life in the ice inside some of the pyramids. Of course, there was no definite evidence for all of this, and Ling Feng didn't take it very seriously.

At least, the tower shows that the ancient Egyptians had an advanced civilization at that time, and that the technology was even more advanced than it is now. Seeing that Ling Feng wanted to stop talking, Li Zhantian said again, "You may have doubts, then let's discuss the Chinese history you are familiar with." ”

&As we all know, the history books tell us that the Spring and Autumn Period and the Warring States Period were the transition period from a slave society to a feudal society, and the productivity of feudal society was inevitably higher than that of a slave society, so that this could represent the progress of historical development, right? ”

This point, Ling Feng could not refute.

The Autumn and Warring States periods may be the most emancipated periods in Chinese history, because at that time, Confucianism, Taoism, Legalism and many other schools of thought presented a situation of a hundred schools of thought, and the ideas of Confucius, Meng, Lao, Zhuang, Han Feizi and others still have a profound influence even now. ”

Ling Feng nodded frequently when he heard this, this is the history that everyone knows.

& Why was there a situation where a hundred flowers bloomed and a hundred schools of thought contended at that time? Li Zhantian stopped his words and looked at Ling Feng with deep meaning in his eyes.

The slave society we know from the history books was a society in which the productive forces were extremely low, the rulers were very brutal, and the people's minds were extremely closed. When the feudal system collapsed in modern Chinese society, countless people of insight also had fierce ideological collisions in order to seek a way to save the country, but it was far inferior to the situation of a hundred schools of thought contending during the Spring and Autumn Period and the Warring States Period. Ling Feng had never thought about this before, and he was indeed a little puzzled at this time. It stands to reason that modern civilization is more advanced and more emancipated, but why is there no ideological **? Can some far-reaching theories emerge in Western society at the time of civilization change?

As if seeing Ling Feng's confusion, Li Zhantian smiled slightly and continued, "Let's look at this problem differently. As the saying goes, only when there is enough food and clothing, human beings have the leisure to think about other issues. Of course, in the history of mankind, there are many people who have made amazing achievements and written far-reaching theories under the extreme hardship of life, but this is not representative of the whole. It is hard to imagine that a person can think about profound academic issues every day without enough food and clothing. ”

At this time, Ling Feng also basically understood the meaning of what the teacher was trying to express, and muttered, "Are you saying that the society at that time was more civilized than in modern times?" More material abundance? ”

There is no historical evidence to prove this, but at least it shows that social thought was more civilized then than it is now. Judging from the rise and fall of the four ancient civilizations, perhaps human beings thousands of years ago may have mastered a more advanced civilization than now, both materially and spiritually. ”

Ling Feng disagrees with this, perhaps from the perspective of the history he knows or the knowledge accumulated in life, these statements are somewhat fantastical and unbelievable, but many unsolvable mysteries in the development of human history show that the teacher's statement may be closer to the truth, otherwise many things cannot be explained at all.

Scientists estimate that the history of the earth is 4.57 billion years old, and the earliest appearance of human beings, it is said that 2.4 million years ago, human writing appeared, which was the Iraqi cuneiform script 5,200 years ago, and the Egyptian hieroglyphs, but then gradually died out. China's oracle bone inscription appeared 3,500 years ago and slowly developed into today's Chinese characters, which is the oldest script in human history today. Due to the production of writing, the communication between people has been closer, and the history of the development of human civilization has been recorded. Li Zhantian and Ling Feng thought for a while, digested the previous content, and then continued, "In the past five thousand years, human beings have developed from the primitive life of drinking blood, covering their bodies with leaves, drilling wood for fire, and living in caves to today's modern civilization with highly developed science and technology, don't you think the speed of development is a bit incredible? 5,000 years is not a long time for the development of human civilization, and in the face of the earth's age of 4.5 billion years, it is even more insignificant, even if the history of human beings appeared on the earth is 2.4 million years, this 5,000 years is really a very short moment compared with it. What have humans done in the previous 2.39 million years? Are our ancestors like the animals in "Animal World" on TV, who only know how to forage for food, sleep, and fight for the reproduction of offspring every day? After spending more than 2.3 million years in this way, suddenly one day, people's intelligence suddenly increased greatly, and writing was created, and human beings all over the world became intelligent people, and they ran like lightning into the slave society, feudal society, and capitalist society that mankind itself later divided. ”

The teacher's words were like a bolt of lightning that swept through Ling Feng's somewhat dazed thoughts. Indeed, there are many unexplained aspects of the development of human civilization, human beings have lived on the earth for millions of years, but civilization suddenly appeared 5,000 years ago, and then developed rapidly. Even if there may be a sudden emergence of wise men to guide the direction of human development, can there be wise men who guide human development all over the world at the same time? Such a coincidence is too sensational. However, Ling Feng had other thoughts and muttered, "This can't rule out the possibility of aliens. "Maybe five thousand years ago, an alien spacecraft suddenly descended on the world to guide mankind towards civilization, after all, in the vast universe, no one can rule out the possibility of alien existence.

Regarding the claim that aliens taught civilization, Li Zhantian did not refute it, but said lightly: "For the ancient history, we can only make bold assumptions and carefully verify it, after all, there is still no conclusive evidence. There is no point in arguing whether human civilization comes from the inheritance of the previous civilization or from the transmission of alien planets. Speaking of this, he paused, as if to organize the appropriate language, "Throughout the history of human development, at least a few points can be clarified, first, there was a high degree of civilization on the earth about 4,000 years ago, and it can be glimpsed from the pyramids and other prehistoric ruins of ancient Egypt, and second, the development of human civilization is not gradual, and there has been a period of rapid development in about 5,000 years, which has led human civilization to this day!" ”

Ling Feng fell into deep thought.

The exploration and reflection of the origin of human civilization should be the concern of experts and scholars, and ordinary people have the strength to pay attention to such problems that seem to be far away from them under the pressure of life. Ling Feng also had the passion to explore when he was studying, but now, how can he have time to think about this? As everyone knows, Li Zhantian is not an ordinary person, since he has become a close disciple of Li Zhantian, he is destined to come into contact with many things that are unimaginable now on the road of life in the future. It's just that at this time, his attention was successfully diverted, and he actually forgot to ask the teacher how he was injured?
