What is the most likely reason all the pyramids were built near Giza and the nile delta?

The pyramids were built near Giza and the Nile Delta primarily due to the region's geographical and logistical advantages. The Nile River provided a reliable source of water and a means of transportation for the large stones used in construction. Additionally, the area’s relatively flat terrain made it easier to construct monumental structures. Proximity to the capital of ancient Egypt, Memphis, also allowed for easier access to labor and resources.
