Mainly because they needed the river for transport and water to sustain them.
They build the pyramids next to the Nile because it was easier to trade and move blocks to the pyramids and the stones could be bought and nearer to the pyramid building site by boat.
The Nile River
The Nile River.
the Nile river.
The Nile runs south to north, pyramids were built on the west bank.
The limestone quarry where they mined the stone for the pyramids had to be relatively close to the pyramids (they could not move the blocks far), and the nearest good stone to be quarried was to be found between the pyramids and the Nile River.
There are two pyramids that stood by the Nile river which is the largest river in Africa. The two pyramids are Saqqara and Giza.
Pyramids were built next to the Nile because the river provided the necessary resources for construction, such as water for the workers, transportation of heavy stones, and fertile land for growing food to sustain the workforce. Additionally, the Nile's flooding provided a natural barrier and protection for the pyramids.
Since the vast majority of the population live in and around the Nile [and the pyramids were built nearby] it is only feasible that burials took place close by - therefore that is where most mummies would be found.
The Egyptian mummies were buried on the west of the Nile River. :)
Actually, they didn't live on the Nile river. They really just lived in palaces that were built by laborers. When they died, they were put in pyramids to RIP. (Rest in Peace)
The Nile River was the main water and food for the Egyptians, who made the pyramids, so, yes, I guess so.
none they were usually built on higher ground so they didn't get eroded
