We are already one race "Creatures." We were created, hence "Creature." A human is one that is self sufficient.
Mankind is not self sufficient we need just about everything to exist. Water, food, oxygen, air, etc. We are ALL DIRT created from dust. "From dust you are and to dust you shall return."
Red dirt, yellow dirt, brown dirt, olive dirt, white dirt, Whatever huge you find your soul/spirit in. God created all of us. One should think about the response to the Creator (God) of us all when you have to give an account for your works here on Earth.
