Why is most farming in ancient and present day Egypt done along the Nile?

My amswer- Because the Nile provided them with fertile land which helped them to grow their crops and raise their animals. The flooding would also coat the land with thick black mud which was ideal for growing crops on. Is this what my teacher is looking for?

Yes, that's a good start. Today, the Nile doesn't flood much because of the Aswan High Dam. But crops are still grown in a narrow area close to the Nile. Now the farmers use irrigation ditches and pumps from the Nile to water their fields.

It's an amazing sight. A road goes between the irrigated fields which are rich and green and the dry, yellow, sandy desert on the other side of the road.
