The earth is a planet in the solar system. It has been 4.6 billion years since its birth. Obviously, human beings appeared after the birth of the earth, so when and where did human beings come from? Human scientists have never stopped exploring these questions, but human beings have never found a unified answer about the origin of human beings.

People used to think that humans evolved from apes. Therefore, it is believed that human beings belong to the land and come from the big forest. This view does have the value of existence. For a long time in the past, people believed that human beings evolved from apes. But in recent years, scientists have discovered that apes are not the direct ancestors of human beings. They believe that when the earth was just formed, there was nothing, including water, air and plants. Then there was water, and the creatures in the water gradually evolved into various animals. Therefore, they think that human beings came out of the ocean.

If the first human came from the ocean, does it mean that the ancestors of human beings were fish? Then can we understand that humans first lived in the sea, then swam to the shallows, then slowly grew limbs, then evolved from aquatic animals to amphibians, and finally lived directly on land? Then after a long evolution, it evolved into the ancestors of human beings, and the ancestors of human beings evolved into human beings?

In fact, many animals we see now have evolved over a long period of time. Where these creatures originally came from is also a difficult problem, which requires more advanced instruments and superb scientific and technological means to understand clearly. This process may take decades or hundreds of millions of years. But what is certain is that it is only a matter of time before the veil of human origin is unveiled with the existing scientific and technological capabilities and the current speed of development. Although our generation may not see it, it is also a relief for our descendants to see it!
