Old Egypt

1) Are the similarities between early Egypt and Sumer so great that the two civilizations ought to be regarded as influencing each other? Why,  or Why not?

I'd say no, for it doesn't seem that Egypt and Sumer ever effected each other. I believe this was mainly because firstly Early Egypt was surrounded by desert and was isolated for the oust part along with Egypt and Sumer being separated by the Medateranian Sea. They were both very different from each other, so they would probably not have understood the other's culture. For instance, Egypt's culture completely revolved around the Nile.

3) How does the architecture of Egypt and Sumer reflect the worldviews of the two early civilizations?

For Egypt, the pyramids reflect their worldview greatly. Firstly, the enormousness of the pyramid shows that the king was  a person of great importance. Then the tomb itself. The way the king is buried along with the hieroglyphics shows three things. Firstly, life after death, secondly, the gods, and thirdly, order life, death, and ressurection.
