If there were prehistoric civilizations on Earth, where did they go?

Of course, man-made civilization has been destroyed by man-made civilization, and if you look at human history, it has always been the destruction of man-made civilization with man-made civilization and the transformation of man-made civilization into relics.

Prehistoric civilizations may have suffered some kind of catastrophe like the dinosaurs and then disappeared from the earth.

Extinct. Because the earth experienced asteroid collisions and glacial periods, life that could not withstand the changes eventually became extinct.

I think it's quite possible that these civilizations have already collapsed. They are lost to history. Obscured by the Earth.

Scientists tell us that the Earth began 4.55 billion years ago. The first life on Earth has been around 3.8 billion years ago. Humans appeared on Earth about 3 million years ago.

Human civilization appeared in a shorter period of time, but only for 10,000 years. After compressing the Earth's long 4.55 billion years into one year, humans appeared around 6 p.m. on December 31. Mankind entered the era of civilization at 23:58:10 on December 31.

At this time, the New Year's bell will ring. The 10,000 years of human civilization is a flash of lightning compared to the long history of the earth. <

Second Age: Mesopotamian civilization was neither Sumerian nor later Babylonian or Assyrian, but appeared before Sumerian civilization. This is a civilization created by the happy people of the Genda civilization.

This civilization was destroyed because of the sudden change in the earth's magnetic field, and the earth had devastating problems. The Sumerian civilization we know now, many incredible things, were inherited from this civilization. Quaternary:

Atlantean civilization. <>

In addition to the records of the Mayans, the Atlantean civilization is also explicitly mentioned in the ancient Greek Plato's "Dialogues", so we have to believe that this civilization may really exist. Atlantis may be an outsider. Not the natives of the earth.

After coming to Earth, there was a serious conflict with the Muria civilization, which led to the demise of the Muria civilization. Incredibly, this collision is documented in detail in the Mahabharata in ancient India. But for some reason, the Atlantean civilization mysteriously disappeared into history, and no ruins were found.

ConclusionThe history recorded by human beings is only about 10,000 years, and the 4.5 billion years of the earth's history can only be expressed with a snap of a finger. <

The above is my personal opinion.

This statement is not necessarily true, because although he has made such a claim, there is no evidence to prove it, so such a statement is not worth believing.

It's true, because we've unearthed a lot of different things, and these things are probably left over from some of the civilizations that preceded us.

Everyone feels that the civilization in the new era is very prosperous and high-tech is also very developed, but I can say that this civilized behavior is too far behind the human technology and civilized behavior in Chinese history. The high-tech creations are really rough and bad compared to the previous civilized behavior. For example, recently, the ancient civilization of our China is the Xiuzhen civilization that directly studied the universe, the body and life, and the development trend has become an extreme shortcut.

Therefore, now people are not transparent in scientific research, and they are becoming more and more incomprehensible.

Some people say that the average microorganism on earth has a long history, but it is intelligent and civilized but has a cycle. Otherwise, how could people create a civilization that has not been able to come out for billions of years, and in just one million years, people have created something that has never been done on earth? Do you dare to ensure that there will not be an infinite number of millions of years in the short time period of billions of years before people?

Taking the civilization of mankind itself as an example, can it not be said that a million years cannot allow a civilized act to come into being and not to destroy a civilized act?

This actually makes sense, although the ancient civilization is a fantasy of its existence, but since there is no very good reason, it is not possible to relativatively attack this kind of imagination. God will select those who are still noble among mankind to survive the calamity and then develop further. The history of human development, no matter how glorious it was, is difficult to store in the midst of the great catastrophe.

The few who remained, could only carry out a new Stone Age on a piece of ruins.

All the tools of labor have been destroyed, all the means of labor have been destroyed, and there are very few skilled employees. Even if there are some great scientists left, they can't do anything to restore all this, because we have lost that scientifically sound natural environment. As a result of the death of smart people, future generations will have less and less basic knowledge.

In addition to the common sense of daily life, a large amount of advanced scientific and technological knowledge has become useless due to the loss of the natural environment on which it depends, and it is likely to die out eventually. After many generations, people finally forgot all this, and gradually created a new civilized behavior from the simple hunting or farming, fishing and animal husbandry daily life in ancient times.

No. Because the Earth's previous environment was not very suitable for living things, and we have found no traces of the existence of any other civilization, I don't think so.

Yes, the earth has existed for billions of years, while human civilization is only about 10,000 years old, and many existing civilizational monuments that cannot be explained by humans also provide some evidence for this speculation.

Before human civilization, there may have been another civilization, but we don't know.
