Lol right like that’s unique to N.America! You think Native Americans are the only population to ever be replaced? if anything that’s more the rule than the exception. Civilizations that were around the same time as ancient Egypt like Sumer, Akkadian all are utterly extinct, there are no remnants left. There are very few like few 1000s of people that claim their decedents of ancient Assyria, they have no great number or power and scattered in 3 different countries! But we’re suppose to sit here and believe that ancient Egyptians are alive and well today...thriving in 100 million in number in their original country! Ha! unless you study ancient civilizations you will not my grasp how absurd your claim is.
Egypt has always been one of the most densely populated areas in the world due to the fertility of the Nile Delta.
Egypt’s population during the New Kingdom(3000-3500 years ago) is estimated to be around 2.5-3 million(there are higher estimates also), and in 1805, the population of Egypt was around 4 million. Egypt’s population boomed to 100 million after the industrial and agricultural revolution, but before that their population remained around the same for thousands of years.
If every Saudi nomad settled in Egypt when they conquered the region, not even 10 % of modern Egyptian’s DNA would be Arabian. Their population was simply too insignificant to make a difference compared to the amount of people living in the Nile Delta region.
