When did human beings begin to live and develop on the earth?

This is the most standard and accurate answer.

Why not tens of thousands, hundreds of thousands, millions of years? Because these are inconclusive, let alone specific time or time period. This time can be accurate to a quarter.

The origin of human beings, the origin of animals and plants, no one can tell, many things are lost fragments. Just like solving a case, we should look for it according to the traces. Once there is no trace to be found, you can only count it.

Nu Wa Eve and other theologies appeared, and all the immortals stood at the commanding heights and did not recognize each other. The emergence of human beings can only appear in one case, which is also * * * learning! So the question is, there must be only one, right? Who is right? None of them are right, and the myth is not credible.

Myth can't be believed, but science should, right? You must believe in science. But science is not omnipotent, and there is nothing we can do about what has passed away. You can only rely on traces to pursue, and once there is no trace to find, it will be embarrassing.

So from thousands to millions of years, we haven't seen which year is the end. Therefore, behind science is speculation, and the film is broken and can't be contacted, which makes many scientists move from atheism to worship the great god. It seems that every Sect has a reason, which is why so many people gather at every altar.

The mystery of theology lies in form. Everything can be said in the final analysis, but it is an empty form, and no one can find the essence. This is the genius of theology. When everything has no solution, asking God is spiritual and mysterious.

One thing still needs to be recognized. When you pray to God, your mind and your past are empty. How can you empty it? Originally, I came with questions. Do you think it's possible to be free?

In fact, it is very simple. This is called sincerity and spirit! When you worship devoutly, everything is cavitating. Some time after cavitation, inspiration appeared and the secret of apple landing was discovered.

So answer: When did humans start living on the earth? No one answered. The only answer is from the moment they were born on the earth.

Why was it the moment when it was born on earth? Because no one knows where people come from, it can only be said that the moment when people are born on the earth is the most standard, because you said that any time is the only possibility, and the possible time is tens of thousands of years, not what year, month and day, not any time is possible, not necessarily, or you can only ask the immortals of various sects, and all the immortals can give a positive result, but you can only trust one, but it will not be like that when you arrive at another.

Ask Darwin! But he will wave to you. His theory of evolution is untenable and the whole world is questioning it. His followers just talk at home, and when they go out, they will make jokes.

Asking this question is tantamount to asking in vain. Why do you ask if you know there is no result? Why do you answer when you know you can't? And no one can answer correctly, only I can.

How big are humans? How many years were you born? Some people say it has been hundreds of thousands of years. In fact, long before this, at least 3 million years ago, or even earlier, humans appeared on the earth. Nowadays, people look for evidence of age in human jaws.

Mao Zedong mentioned in the article "On Chongqing Negotiations" that human beings have been born for 500,000 years. According to the archaeology of Beijingers, China historians also believe that human beings have been born for 500,000 years. According to the fossils of "Javanese Ape" and "East African" in Tanzania, foreign historians infer that human beings have been born for 3 to 5 million years. So how big are humans?

Since 1973, a large number of human fossils have been unearthed in the strata of Hada area in Ethiopia from 3.3 million to 2.9 million years. Scholars believe that some of them can be regarded as human ancestors, and the bones unearthed in the same place also lived about 3.5 million years ago. 13 fossils belonging to human system or primitive man were unearthed in Lille, Leto, which is more than 40 kilometers away from Ordway Canyon. Among them, the inferior cis bone was identified as a human genus, dating from 3.35 million to 3.75 million years ago.

A 5 million-year-old fossil of ancient human jaw was found in Kenya. Anthropologists from Harvard University in the United States who participated in the excavation said that previous excavations showed that humans existed in East Africa three or four million years ago, and this time, the unearthed jaws pushed forward the appearance time of human beings on the earth by 65.438+0 million years.

Although there are no stone tools attached to these bones, from the overall situation, through the analysis of fossil morphology and function, it is judged that they belong to "human genus" According to the viewpoint of "wooden tools came first", they were transformed into adults by making wooden tools. So the age of human beings is not two or three million years, but three million years, or even four or five million years.

To sum up, although the age of human beings is 500,000 years, 6,543.8+0,000 years and 23 million years. 3 million years ago and 4 million years ago, but neither can be used as a conclusion. Because although the theories of 500,000 years, 6.5438+100,000 years, 23 million years and 3 million years have been rejected one by one with the increase of archaeological data, the theoretical evidence of 3 million years ago and 4 million years ago is still insufficient.

However, with the continuous enrichment of archaeological and anthropological data, the theoretical basis of 3 million years ago and 4 million years ago will definitely increase. According to the data available in East Africa, the age of human beings was not two or three million years ago, but three million years ago. Or longer. As for how much it can be advanced, it is still difficult to determine.

I remember living on the earth since I was sensible.

When there is life on the earth, human beings began, but the way of existence is different from now. Without the most primitive creatures, there would be no human beings in this world.

That was a long time ago. It's also what I know [yi tooth]

Never.

Humans evolved from apes, but there is no clear dividing line between them. In other words, there is no point in time to distinguish between humans and apes.

It is generally believed that humans appeared about 2.5 million years ago.

The people here depend on how you define it. If you are like us, it can only be Homo sapiens, and it refers to late Homo sapiens, such as cavemen who left Africa more than 40 thousand years ago. The reason why they all came out of Africa may be related to the climate at that time. At that time, only Africa was suitable for a large number of hairless mammals like humans. Homo erectus millions of years ago, such as Beijingers, is not the same species as human beings today.

This definitely needs archaeological evidence. It's hard to say if you just answer from the perspective of conjecture. Actually involves the process of civilization. The history of modern human civilization does not exceed 5000 years. Verifiable archaeological evidence of humans or apes can be traced back to 4 million years ago, but perhaps humans will exist for a longer time. . . .
