Humans evolved unconsciously for a long time, but as soon as they developed language and oral history, rudimentary government and the ability to argue, natural evolution ceased. That meant it ended long before Darwin ever noticed it had existed. In fact, it ended long before Creationism was invented. The rules that were supposedly handed down by God were devised by people who had been shaping their own course already for thousands of years.
You could say that by the time we started getting serious about keeping track of God's word we had long since decided to defy it.
