Evolution does not have all the answers. Creationist especially like to say that we, the evolutionists, cannot account for some aspects of the origins of life on Earth; and that they can. They are absolutly right, we can’t and they can. But then that’s the burden of being science: we only know what we observe in the natural world. Creationists on the other hand can simply refer to the Bible for all of there answers - looking to the natural world only to reaffirm their beliefs.
You may think this would put evolutionists at a disadvantage. Not being able to answer some very important questions. Hardly. By accepting Genesis as an acurate account of the ‘origin of species’, they have backed themselves into a corner which they must defend. While evolutionists can change their view to fit new evidence - creationists must find new and creative ways to insert new scientific discoveries into their origin story, often with hilarious results (early hominid fossils were just really old people).
