If a god had created all peoples, but He (it's invariably a He) had chosen only one people, and not exactly the most numerous one, would that god not be something of a xenophobe?
After creating all races and choosing only one people, would an omniscient god reject his own previous decision and then choose everyone?
In my humble opinion, God created no races and no peoples. But some guys in Canaan decided they were more special than all the other peoples who have considered themselves special, and they put that in writing. Later on, some guys who were not of the *Special* Class, a.k.a. Gentiles, decided that they were *Special* after all, and pictured that God just as they were: white.
In a country that I won't identify, where people do not usually have blue eyes, Jesus is thought to have blue eyes. That is what these people learned from those who gave them Christianity.
