This isn’t a question of faith so much of science. All the scientific evidence points to our species arising in Africa. It’s almost laughable to assume Adam and Eve would have been “white”.
To this day, there is far more genetic diversity among humans in Africa than elsewhere on the planet. A small group of Africans left Africa at some point, perhaps 50 000 years ago or so, and slowly spread out across Europe, Asia and the Americas. As groups become isolated from one another, through the process of genetic mutation and natural selection, different physical characteristics emerged. Europeans and Asians remain very closely related… more so than distinct groups of Africans are to each other.
