Another point to add to this is that the Nile River is significantly easier to manage for the Egyptians than the Yellow River was for the Chinese. Unlike the Nile River that flows along the same path and floods the same areas every year, the Yellow River has a nasty tendency to change its mind about where it wants to flow into the sea, and it destroys all the farmland along its path when it shifts its outflow from the north side of the Shandong peninsula to the south and back again a few hundred years later. That widespread flooding and shifting of the rivers path makes the entire North China plain very fertile compared to a thin strip along the Nile, but it also causes widespread damage and casualties whenever a bad flood year shifts the Yellow River's path down the middle of a town.
