What is the contribution of the river Nile in Egypt civilization?

The Egyptian Civilization was brought upon the banks of the Nile River. It was considered as a holy river, just as the Ganges, as it is associated with prosperity and well being.
The river aided in the rich crop production- up to three crops in a year due to the irrigation provided by the river, with the cultivation of cotton, oats, bajra, onion etc. It was thus famously known as the ‘Granary of the World’ due to this.
