The berber people are indigenous to that area too they're not colonizers from Europe or the Middle East. Also there's a lot of different groups . Some of the are black like Tuareg.no one really knows
no one really knows what race but I think the native Berbers where and still are black. Black people traverse that area first. I can't think of any reason why A light skin white person can beat native African people to that part of Africa. It doesn't make sense to me.
And some are light skinned like this girl
(Note the ink, they're culture's tattoo's are so cool imo.)
