8000 BCE: (The Divergence of Proto-Boreafrasian in Egypt — The Ancestral Boreafrasian Language Continuing to Be Spoken in Egypt Eventually Diverging into Two Lines of Descent, One Giving Rise to Proto-Chado-Amazigh Ancestral to the Chadic and Amazigh Subgroups, the Other Leading Down to Ancient Egyptian Itself, the Initial Westward Divergence of the Chado-Amazigh Branch Fitting with the Early Holocene Epoch of Around 10,000 Years Ago When Wetter Conditions Allowed Settlement Across Large Parts of the Northern and North-Central Sahara): The ancestral Boreafrasian language, which would have continued to be spoken in Egypt after the departure of the pre-proto-Semitic speakers, eventually also diverged into two lines of language descent. One gave rise to the common ancestor language, proto-Chado-Amazigh, of the Chadic and Amazigh subgroups of the family. The second line led down to ancient Egyptian. The initial divergence of the peoples of the Chado-Amazigh branch, westward from Egypt, can be proposed to fit in with another era of cultural spread: the early Holocene epoch of around 10,000 years ago. This time of climatic shift to wetter conditions allowed for the settlement — evident in the archaeology of that period — of people and their cultures once again across large parts of the northern and north-central Sahara. The communities who remained in Egypt would have spoken the language that would evolve over the next several millennia into early ancient Egyptian. Here is the final branching of the family tree that produced the language of the pharaohs. Ancient Egyptian was not the trunk of the Afrasian tree but its last remaining branch in Egypt — the language of the people who stayed while the Chado-Amazigh speakers moved west into the greening Sahara and the pre-proto-Semitic speakers had already moved northeast into the Levant. The Egyptian language is what remained after the departures, the linguistic residue of a community that had been shedding daughter populations for seven thousand years — northeastward, westward — while itself remaining rooted in the Nile Valley, deepening its relationship with the land that would become the stage for one of history’s most consequential civilizations.
