What is the difference between Eygpt and Nubia

The Nubian were a different civilization although debate gos back and forth about which came first we do know a few key differences. 1nUbian women had more right then Egyptian, some were Pharaohs, some lead wars. And in every picture of a royal with him was shown his mother and wife. 2 Nubia’s land was rich with iron copper and gold which they used to make jewelry and trade with Egypt and they used the iron for iron weapons (later used to defeat the Egyptians) 3 Nubian pyramids are steeper and quite small compared to Egyptian pyramids. Also pyramids were for not just the royal in Nubia but any one who could afford it. Which wasn’t that much because Nubian pyramid were made with sandstone (instead of Egypt’s lime stone and mud brick) And those are some differences between Nubia and Egypt.
