Immigrating to Zhihu Lake in Africa.

This is because the climatic conditions in Africa are very bad. Moreover, there were many wild animals at that time, which posed a great threat to human survival and development, so many humans chose to leave Africa. However, people who fled invented writing in the process of migration. And then went to the civilized world. This is mainly because humans who left Africa found a place more suitable for human habitation and survived here. But those who stayed in Africa did not develop civilization.

Even the present civilization in Africa was brought by western colonists through the era of great navigation. Otherwise, Africa is still a backward tribal civilization. In addition, the communication between African tribes is not very extensive, resulting in great differences in writing, language and culture. However, due to the impact of western colonists, African tribes were forcibly unified and the cultural ideas of western colonists were forcibly accepted. However, due to the great cultural differences between western colonists, African tribes still have great grievances.

But human beings who left Africa survived in suitable places, invented written language and modern culture, and formed a modern civilized society. It also makes people outside Africa far smarter and wiser than Africans. This is because people outside Africa must strengthen their minds and bodies, because the challenges and risks they accept are much greater. Defend our tribe and even our country.

Such long-term development will make the development of human beings outside Africa far higher than that of human beings in Africa. This is the inevitability of historical existence, because the climate in Africa is very hot, which also causes Africans not to love labor and work. In the long run, Africa will become very poor and backward.
