How old is our government system similar to that of the Egyptians?

The government system of ancient Egypt dates back to around 3100 BCE, when the first pharaoh, Narmer, unified Upper and Lower Egypt. This means that their system of governance has been in existence for over 5,000 years. While modern governments have evolved significantly, some foundational elements, such as centralized authority and administrative organization, can be traced back to ancient civilizations like Egypt. However, contemporary governmental systems are distinct and influenced by various historical, cultural, and political factors.
