The first pyramid in ancient Egypt was built in 2650 BC, more than 600 years earlier than the recorded Xia Dynasty in China. But at this time, China was in the mythical era, probably the Dayu era.
However, according to other records, the inscriptions on the double piers discovered by Chinese archaeologists at Qingdun site are about 6000 years ago, the bronze knives discovered at Majiayao site in Gansu are about 5000 years ago, and the third culture of Xuejiagang in Anhui is about 5 100 years ago. If these records can be recognized, it can be said that Chinese civilization was earlier.
The results of archaeology are to be determined, which are mainly based on the view of professional world identity. But in any case, these two civilizations are now recognized as the oldest and longest-lived civilizations.
About 6000 years ago, many small slave countries appeared near the Nile in ancient Egypt. After a long period of war and annexation, the narrow Nile valley was divided into two great powers: upper Egypt and lower Egypt. Around 3 100 ad, war broke out in upper Egypt and lower Egypt. After this battle, Upper Egypt completely realized the unification of Egypt. Egypt experienced three important periods in the later period.
