- The Historical Process of Mankind (II)
The earth that mankind now understands is 4.5 billion years old!
The original Earth, very close to the Sun, also rotated and rotated extremely fast, and was always in a state of combustion and dissolution.
It has only been in the last few million years that the Earth has begun to stabilize. It moved away from the sun and the moon, and the speed slowed down. The water vapor in the sky has also condensed into rain, the gas in the air has become lighter, and the magmatic activity in the ocean has gradually weakened...
At this time, human beings were still not born. Because surface water is still very limited. It was not until a certain period of time, when small streams appeared on the rocks, rushed forward, and converged into rivers and lakes, that it was possible for humans to appear.
Nature continues to work hard, and after a few million years, the earth is getting older, the climate is getting milder, and the first creatures appear in the oceans.
