Why do some Christians insist evolution is based on chance alone?

There seems to be a basic misunderstanding of evolution, especially by some persuations of Christianity. Evolution is not a statistically improbable chance event. The driver of evolution is NATURAL SELECTION, an combination of extremely powerful forces of nature that determine whether a mutant organism survives to reproduce. The only role chance plays in evolution is the placement of mutations in the genome. We all suffer mutations every day, about 10,000 in your skin per day if you are exposed to the sun. Evolution is NOT about chance, it is about changes in genes chosen by natural selection.
