Everything about prehistoric civilizations? How many years are included?

The most direct is that the moon is a product of prehistoric man.

How many years ago did prehistoric civilizations generally refer to?

Prehistoric civilization refers to the era before the emergence of writing, about 4000 BC, before which there was no recorded history of mankind. About 750 miles south of the island of New Caledonia, about 750 miles off the east coast of Australia, there is a small island called Pine.

There are more than 400 strange anthill-like mounds on the island, made of sand and stone, 8 to 9 feet high and 300 feet in diameter. There is no grass on the ancient mound, and no remains can be found in the ancient mound, only an upright cement cylinder was found in each of the three ancient mounds. Two cement columns side by side were found in another mound.

These cylinders range in diameter from 40 inches to 75 inches and are 40 inches to 100 inches high. Determined by radioisotope carbon testing, the cylinders were from 1095 to 5120 BC. Who used cement before it was invented?

What exactly are these cylinders for? Why can't I find any related human relics nearby? Discover a secret tunnel system in South America.

The secret entrance to this tunnel system was guarded by a tribe of Indians and led to a depth of 250 meters. The inner walls of the tunnel are smooth and smooth, and the top is flat. There are several wide halls and holes, which are as huge as jetliner hangars.

In a hall 153 meters wide and 164 meters long, there is a table and 7 chairs. These tables and chairs are made of unknown materials, like stone but not cold, like plastic but hard as steel. In the U.S. states of Florida, Georgia and South Carolina, a wide, flat avenue was found.

The submarine can be moved on the avenue like a bus when it is on wheels.

According to historical records, it took no more than 10,000 years for our human beings to go from the most primitive Stone Age to the emergence of the current high civilization. Obviously, these monuments of civilization do not belong to us as human beings. In fact, there are many monuments of civilization that we are not able to build with human science and technology.

Based on this conclusive evidence, some scholars have proposed the doctrine of prehistoric civilization, which refers to the existence of human civilization on Earth before our current human civilization.

At the same time, many of the monuments of civilization found are very ancient in time. Judging from the various relics of prehistoric human civilization excavated and discovered today, human beings have always existed on our earth and developed highly developed civilizations since a very long time ago. For example, the 600 million to 100 million years old human footprints in shoes found on the trilobite fossils, the 2 billion year old large chain nuclear reactor found in today's Gabonese Republic of Africa, the 2.8 billion year old metal balls found in present-day South Africa, and many stone tools from different periods, etc., it is difficult to imagine that they belong to the same period of human civilization.

Therefore, scientists have put forward the theory of many prehistoric civilizations, believing that there were many prehistoric humans and civilizations on the earth. The development of human beings is not as previously imagined, but cyclical, and there are different civilizations on the earth at different times.

Modern science has recognized that everything develops in a cyclical nature. People are born, old, sick, and die; Plants and animals also have birth, old age, sickness, and death; The development of society is cyclical, and the development of human beings is likely to be cyclical. Clues to this can be found in the various remnants of different prehistoric human civilizations excavated and discovered today, as well as the tools left behind by different prehistoric human Stone Ages.

In his book "Galactic Encounters, Apollo Objects andatlantis: A Catastrophical Scenario for Discontinuities in Human History", scholar Emilio Spedicato provides an in-depth analysis of the causes of the destruction of prehistoric humans. Causing anomalies in the earth's climate may lead to the destruction of human civilization.

However, what is clear is that these different prehistoric humans and the civilizations they possessed eventually disappeared from the face of the earth. At different times, the catastrophes of the earth destroyed the civilization of that time, and even exterminated the vast majority of the living things at that time, leaving only a very small number of survivors. So why are these civilizations eliminated?

How to be eliminated?

Did prehistoric human civilization disappear?

Prehistoric civilization refers to the remnants of various civilizations of different periods that existed on the earth. Based on archaeological discoveries and research, scientists have put forward the theory of prehistoric civilization, and some believe that human development is cyclical, and different civilizations exist on the earth in different periods; Others believe that humans have a single ancestral origin.

Many of the monuments of civilization discovered by mankind span a very long period of time. From the various relics of prehistoric human civilization excavated and discovered today, human beings have always existed on the earth from very ancient times, and highly developed civilizations have developed. For example, it is difficult to imagine that the human footprints wearing shoes between 600 million and 100 million years ago found on the fossils of trilobites, the 2 billion-year-old large-scale chain nuclear reactor found in the Gabonese Republic of Africa in the 21st century, the 2.8 billion-year-old metal balls found in present-day South Africa, and many stone tools from different periods, etc., it is difficult to imagine that they belong to the same period of human civilization.

Therefore, scientists have put forward the theoretical conjecture of many prehistoric civilizations, believing that there have been many prehistoric human civilizations on the earth, and human civilization is cyclical.

The prehistoric period refers to the period before the Three Emperors and the Five Emperors, about the 30th century BC.

Prehistoric civilization refers to the era before the emergence of writing in human nuclei and generally refers to the worship of heads before the fourth millennium BC.

Prehistoric civilization is a prehistoric civilization conjecture put forward by scientists based on the various prehistoric human civilization relics excavated and discovered today, believing that the development of human beings is not as imagined in the past, but periodic, and there are different civilizations on the earth in different periods. Many of the monuments of civilization discovered by mankind span a time span that is not the number of Liangs. From the various relics of prehistoric human civilization excavated and discovered today, scientists have found that since very ancient times, human beings have always existed on the earth, and highly developed civilizations have developed, so they have repeatedly put forward the theoretical conjecture of prehistoric civilization, believing that there have been many prehistoric human civilizations on the earth, and human civilization is cyclical.

Prehistoric civilization refers to the era before the emergence of writing, about 4000 BC. Many of the civilization monuments discovered by human beings span a very long time, from the various prehistoric human civilization relics excavated and discovered today, from very ancient times, human beings have always existed on the earth, and highly developed civilizations have developed.

Modern science has recognized that everything develops in a cyclical nature. People are born, old, sick, and die; Plants and animals also have birth, old age, sickness, and death; The development of society is cyclical, and the development of human beings is very likely to be cyclical, and clues can be found from the various relics of different prehistoric human civilizations excavated and discovered today and the tools left by different prehistoric human Stone Ages. However, it is extremely clear that different prehistoric human civilizations eventually disappeared from the face of the earth.

At different times, the catastrophes of the earth destroyed the civilization at that time, and even wiped out the vast majority of living things at that time, leaving only a very small number of survivors.

The chronological range of the prehistoric period is the history of mankind before the advent of writing. And the emergence of writing in various parts of the world has come and gone. So the lower limit of prehistoric archaeological research is different around the world.

For example, the prehistoric period of ancient Egypt ended in the second half of the 3000s BC, and the prehistoric period of China ended in the 21st century BC. Generally speaking, the prehistoric period of China is roughly divided into the Neolithic and Paleolithic periods, while in most parts of Europe and most of Africa, the prehistoric period includes not only the Stone Age, but also the early Iron Age.

The Xia Dynasty began with the development of slave society to the present day.

5,000 years of civilization began when there was writing.

China's 5,000-year-old civilization, of course, began with records, otherwise how could it be handed down through the ages!

China: 841 BC.

Ancient Greece: 776 BC.

Ancient Rome: 753 BC.

Ancient Babylon: 747 BC.

Ancient Egypt: 664 BC.

In 841 BC, the first year of the Western Zhou Republic.
