Do you have any references for that claim? I wasn't aware that the Berbers, who've been there since the Stone Age, were predated by the Jewish people.
Amazigh were the nomads who lived in North Africa in tribal settings, so they didnt have clear borders or nation like we have it now.
Once egypt grew to big and arrogant it is also the Amazigh who cut their trade routes to deeper Africa, which caused the decline and fall of that great empire.
disclaimer: my spouse is trained by master Amazigh storyteller to be one of first female storytellers. they have fascinating stories. A lot of history and tradition encoded in old contexts. (stories about animals and nature mostly)
