Every spring, far away in the highlands of Africa, waters began to rush downstream. As they flowed, they brought rich, fertile sediment called silt. Silt is fine soil that is found at the bottom of rivers. By late summer, the Nile spilled over its banks all the way to the delta. The flood waters deposited a thick layer of silt making the land the best area for farming. Making it wet and gets good soil is the best.
It also is an area where the Egyptians made a trading post there.
The Nile also attracted animals which made it easier to hunt.
