How do achievements in architecture in mohenjo-daro and in anceint egypt both reflect the process of state-building?

The Mohenjo-Daro is an archeological site in the province of Sindh, Pakistan. It was one of the largest settlements of the ancient Indus Valley Civilization and one of the world's earliest urban settlements. It was built at the same time as the civilizations of ancient Egypt. The architectural structures of both the Mohenjo-Daro and those of ancient Egypt are advanced. The way the Egyptian tombs were built proves that both ancient civilizations are comparable with modern civilization and architecture.
