Currently, science is the authority. Unfortunately, the religious perspective of humanism has established itself exclusively as the legitimate user of science. Consequently, an atheistic bias has become erroneously synonymous with science, thus, evolution prevails as the origin model of choice, not because it is right or because creation is wrong. Evolution and creation are contradictory models. Evolution proposes that the origin of the universe, of life, and of all forms of life are the result of the natural properties of matter.
Creation proposes that the origin of all things is the result of a supernatural event.
Though questions of who and how of supernatural origins are issues to be sorted out in religious circles, the question of whether origins is best explained by natural or supernatural events can be resolved by means of modern science. Science is a tool and is not inherently theistic or atheistic. It should be used to discover truth not to censor unpopular models. Recognizing the important role science plays in verifying and offering credibility to systems of thought, science is the very tool needed to resolve the debate between natural and supernatural models of origins. If you study the literature regarding the controversy over origins, you have probably heard the accusations that evolution is not science and that creation is not science.
