What kinds of similarities were there between the cultures of Nubia ans Egypt?

They are simillar because they both belived in one god and they both most likley built pyramids

A few things that are similar are first they both trade things, there both powerful countries and yes there both lands in Africa; ). A few differences are the physical land, the culture government, the people, a lot of others things I'm sure if you put your mind to it you can figure out.
