Decent article. But the “ancient Egyptians” were genetically and culturally very different from the arab Muslim invaders who wiped out the “ancient Egyptians” and replaced them. There are few descendants of the Egyptians who built the pyramids alive today.
Yes, if they go full muslim and implement sharia law, they will wipe out the remaining Christians and destroy the Sphinx and pyramids.
This is what muslims do.
Inaccurate. As with most conquests, the Arab invaders imposed themselves as a tiny ruling clique at the top. The vast majority of Egyptians alive today are largely the descendants of the ancient Egyptians.
Genetically speaking, that is. Culturally and linguistically there is almost zero continuity, as the Muslims gradually assimilated the Egyptians.
Arabia is and always has been sparsely populated. There is simply no way that they could ever have conquered and displaced, physically speaking, the inhabitants of such far more heavily populated lands as Syria and Egypt.
