The Tower of Babel, of course. When God made everyone speak different languages, He also made them all different races and sent them all over the world.
When a story simply doesn't make sense, just insert the phrase "God did it" and it'll all work out.
Better than my answer: evolution. But of course it the planet's less than 6,000 years old evolution wouldn't have had time to create the myriad of ethnicities.
