I think the Egyptians were fascinated with death because it was a very mysterious thing back then. They didn’t have anyone to teach them about God and his love for them. They were possessed by Satan’s demons and they needed someone to help. That is why when Moses came he freed them all. If they knew God then they would have not done the things that they did. God would have helped them but they wouldn’t listen.
They also believed in the two spirits called the ka and the ba. I know it sounds weird but it’s true. Well that is all! bye
