Egyptian culture was inseparable from the Nile River. It was a source of water, provided fertile soils for agriculture, fish were a ready protein supply, and the bullrushes that grew along its banks provided material for baskets, floor mats, and other Egyptian stuff.
But heck, you gotta suppose that Egyptians used it for fun too. Swimming might not have been a great idea because the Nile was home to crocodiles but how about hopping in the family yacht and going for a cruise. Egyptians must have done that. And one of the objects in our museum’s Egyptian exhibit is a large (4-feet long) wooden model of an Egyptian boat, complete with several people standing on deck. It seemed that sketching it was the right thing to do. Hope you like it.
