Because egyptains along the Nile river grew crops around it because the soil was rich and was good to grow crops on. They also fished for catfish and perch egyptains. Many people living along the Nile River washed their cloths in the river . They also bathed them selves at the Nile River,kinda embrassing you think, getting undressed in front of other people, it also would be wierd if u didn't even know the person who was getting undressed right by you. I don't think I would feel right getting undressed in front of other people, they also bathed animals such as camels & donkeys.
