Have advanced civilizations ever ruled the earth?

There is no direct evidence as to whether there are aliens in the universe, but scientists firmly believe that aliens are real. In the universe, the earth is just a very ordinary planet. If such an ordinary planet can give birth to human beings, then other planets will definitely give birth to civilization.

The earth has a history of 4.6 billion years since its formation. This is considered a young and middle-aged person in the universe. Human beings have only appeared on the earth for a short time. So in such a long time on the earth, Has there ever been a human civilization?

Archaeologists have discovered ancient nuclear reactors on the earth, as well as some artificial tunnels that have existed for billions of years. These tunnels and some civilized buildings that appeared in ancient times have led scientists to speculate that the earth It was ruled by an advanced civilization 2.2 billion years ago.

2.2 billion years ago, a group of advanced civilizations from extraterrestrial planets arrived on the earth. At that time, they were attracted by the earth’s comfortable climate, and in such a large environment Next, they began to have the idea of ????preparing to settle on the earth, so they began to build many strange and weird buildings on the earth. In the end, after these advanced civilizations left the earth, they could only use these buildings to find the original lost civilization.

There is also a saying that in the 4.6 billion years since the birth of the earth, before the emergence of human beings, several generations of civilizations had appeared. Scientists call it prehistoric civilization. The theory of prehistoric civilization has been around for a long time, and the nuclear reactors and artificial tunnels discovered billions of years ago by archaeologists may be the products of prehistoric civilization.

The most developed civilization that has ever appeared on the earth may be the first generation of prehistoric civilization not long after the formation of the earth. The development history of this civilization far exceeds that of human beings. There is a hypothesis that civilization was born on the earth 2.2 billion years ago. The development process of this prehistoric civilization was the same as that of human beings, passing through primitive society and feudal society. Later, there were several industrial revolutions, and we stepped out of the earth and began to explore the universe.

With the rapid development of technology in prehistoric civilization, the earth’s energy is no longer enough to meet the needs of civilization. At this time, prehistoric civilization already had interstellar spacecraft that could travel far, so prehistoric civilization made a decision. He left the earth with all his life and embarked on the journey of interstellar immigration, heading towards the center of the galaxy.

Sailing and developing along the way, the technology of prehistoric civilization is also developing rapidly. After hundreds of thousands of years, it finally reached the center of the galaxy. Later, after countless years of development, prehistoric civilization has become The real overlord of the galaxy is already an established advanced civilization.

After the departure of prehistoric civilization, the earth has developed for more than 2 billion years. Human beings have appeared and a new reincarnation has begun. Although this guess is a bit bold, it is not necessarily impossible. After all, what happened billions of years ago does not directly indicate who is right and who is wrong. It is all a guess. Perhaps after hundreds of thousands of years of development, human civilization will be able to travel to every corner of the universe and reach the center of the Milky Way, and meet various civilized races, and perhaps gain a new understanding of the history of the earth.
