Ehhh my comments was meant to point out that Egypt was far from an "unbroken span of time with the same name and identity." The region was conquered multiple times with numerous fractures and centralisations happening. Cleopatra didn't feel a need to construct a pyramid tomb for herself for example, that culture has died off and been replaced .

A lot of people in Europe speak languages that have a lot of latin words, so is the EU the same thing as the Roman Empire?

We are talking about a people living in a region having various civilizations over thousands of years so I think it's a better comparison.
