So that before human beings appeared, the earth had enough time to breed other intelligent life, and these life also had enough time to develop and evolve their own civilization, and finally disappeared in the long river of history, and the traces that once existed were erased by long years.
Of course, the reason why prehistoric civilization theory convinces many people is not only the conventional logical way of human beings, but also some ancient records left by ancient civilizations and many extremely horrible details. Let's look at three prehistoric civilizations that may have existed.
First, mainland civilization.
"mu continent" is also called "mu continent" or "mother continent" by many people. This concept was first put forward by American scholar james churchward in the early 20th century.
Chai Wuji believes that the mainland is vast, starting from the present Hawaiian Islands in the east, reaching the Mariana Islands in the west, and reaching Fiji, Tahiti Islands and Easter Island in the south.
The mainland is about 8,000 kilometers long and 5,000 kilometers wide from north to south. In this way, its area should be similar to that of the American continent today, about 35 million square kilometers.
Today's mu mainland is located in the vast sea because of a strong earthquake and long-term crustal changes about tens of thousands of years ago, which left the originally fertile mu mainland only fragmentary and gradually sank to the bottom of the sea.
However, with the proposal of plate tectonic theory and the continuous exploration of submarine plate by human beings, the statement of "mu continent" has been denied by many mainstream theories.
However, it is extremely frightening to think that although the "Mu continent" does not seem to exist from a geological point of view, there are many buildings on many small islands in the Pacific Ocean that are the same as those in the American continent. For example, there are altars on Tuamotu Islands that are very similar to Mayan pyramids.
You know, the Tuamotu Islands are far away from the American continent where the Mayan civilization is located. Thousands of years ago, how did people on Tuamotu Islands build altar buildings similar to Mayan civilization? Or why are the altar buildings similar?
More importantly, the legend of "the sinking of the big island" is circulated on almost every small island in the Pacific Ocean. According to legend, there are gorgeous people living on the big island, and there are many magnificent buildings and even flying boxes.
Then the question is, will the big island mentioned in the myths circulating on various small islands be the legendary "mu continent"? If so, it can be relatively reasonable to explain why there are buildings on the Pacific Island similar to those on the distant American continent, because the American continent is relatively close, and the possibility of mutual communication between the two places cannot be ruled out.
But in this way, a new problem has emerged. The mainland of Uzbekistan was tens of thousands of years ago, while the development of human civilization was less than 10 thousand years. Who lived on the mainland of Uzbekistan tens of thousands of years ago and established civilization? Is it prehistoric civilization?
In fact, there is another evidence that Austronesian languages once existed. Austronesian language family is the only language family distributed on a small island on the earth, and its distribution range is exactly the theoretical position of the mainland. Isn't this a little scary?
Second, the Lemurian civilization.
The land of Lemuria is also called Lemuria or Lemuria. Like Chinese mainland, it only exists in various ancient books.
According to ancient records, Lemuria is located in the Indian Ocean, which was once close to Hainan, China. It ended the same as the mainland-sinking into the sea floor.
According to many mysterious works, people living in Lemuria attach great importance to the "love and harmony" lifestyle, love artistic creation and have made outstanding achievements in many artistic fields.
Many people who firmly believe that Lemuria once existed think that people living in Lemuria are not human, or not pure human, because they are very thin, which is why they hide underground. After all, there were many large wild animals active on the earth tens of thousands of years ago.
Supporters believe that almost all civilizations on earth have been inspired by Lemurian civilization, including Sumerian civilization and China civilization.
Of course, although Lemuria has many supporters, its existence has not been recognized by the scientific community, because many scientists have not found that there was an independent continent in the Indian Ocean in 654.38+million years.
Third, Atlantis civilization.
Atlantis civilization is believed to be familiar to everyone and often appears in various film and television works and games. The earliest record about it comes from Plato's book Dialogue.
In fact, not only dialogue, but also the mysterious Atlantis was mentioned in two books written by Plato in his later years, Cletus and Timaios.
According to Plato, Atlantis lies across the Strait of Gibraltar today. It is a vast and lush continent, but in an accident ten thousand years ago, Atlantis was swallowed up by a flood and sank into the cold sea forever.
In fact, it is not difficult to find from Plato's records that Atlantis is definitely a highly developed prehistoric civilization, because more than 10,000 years ago, they already had perfect ports, advanced ships, and even tools capable of manned flight.
What is even more shocking is that they had an energy system running through the whole city more than 10 thousand years ago. In many parts of the city, there is an energy collection and release device called "magnetic Oushi", which can convert the received sunlight into various energy that can be used by people, and then release it to all corners of the city for people to use.
As we all know, judging the level of a civilization is mainly based on the level of productivity and energy use, so Atlantis civilization is definitely a highly developed prehistoric civilization.
In fact, compared with other prehistoric civilizations that may have existed, Atlantis civilization has the most evidence. For example, in 1967, American pilots found huge and regular rectangular buildings underwater when flying low in the Bahamas of the Atlantic Ocean. The next year, an expedition found an underwater temple near Andros Island, which was similar in shape to that seen by pilots.
At the same time, the expedition team also found a rock platform that sank 30 meters underwater near Bimini Island. From this, the expedition came to the conclusion that there must be a large-scale building complex near the Bahamas in the very distant past.
In addition to the above sporadic discoveries, scientists have also found many rock buildings on the bottom of the Atlantic Ocean. These buildings include city walls, wide roads, docks, etc. Their arrangement is very similar to Plato's description of Atlantis.
The above three are the most authentic three prehistoric civilizations. Of course, although they are likely to exist, and some even have detailed ancient records, their existence is still only a guess, or a beautiful yearning, until further discovery.
