I'm not a young earth creationist (YEC). Myself, I accept evolution and believe it was God's tool for creating humans and the variety of life on Earth. Some people like YECs believe Genesis is a literal account of human history. For those of you who believe this, what is God's explanation for creating different races? Wouldn't it be more effective to just create one color/ethnic group? Considering that racism wouldn't exist if we were all mixed into one race, it's a genuinely good question.
Skin color is a delineation we use to divide people. There are so many differences in people, everyone has unique features, such as: hair color, hair type, ear size and shape, eye color, eye shape, nose size, lip size, mouth contour, chin prominence, skin hair, skin pore size, skin color, skin freckles, shoulder shape and girth, etc, right on down the line and many others I missed along the way.
Everything God creates is diverse, just as no two humans are made the same, there are also no two identical hills, rocks, trees, flowers, dogs, fish, clouds, or whatever.
Man is the only creature imposing some special meaning on the color of skin. Why should we even consider transferring our sin in that matter on God as if He's somehow at fault?
