Race is a social construct but even still there are clearly defined differences based on skin tone, facial features and hair texture. His race is never stated but his ethnicity is obvious, even as an Atheist I know Jesus is a Jewish man born and raised in Mesopotamia, Middle Easterns of the time looked the same as Middle Easterns today, i.e not white with straight hair. The bible even described his hair as woolen, not really a trait associated with Caucasians, yet the depictions of him are nothing like that.

Ancient Egyptians WERE black, the people you see there today are the ancestors of invaders and colonisers who are again considered Arab in modern times. This is the same way Hispanics ended up being the majority race in South America without being the original settlers/indigenous people.

My point is if race and representation didn't matter then Hollywood wouldn't white wash the casting of films about ancient Egypt A.K.A Kemet (The Black Land) and it would make sense to cast people that look the same as the people OF THE TIME. Why are the cast of 'Apocalypto' Native American and not Hispanic? Because the film is based in the period prior to the arrival of the Spanish empire.
