Good point:"Indeed, the fact that there are brilliant scientists who believe in God and brilliant scientists who don't makes it clear that the conflict is not a simplistic one between science and religion, but between opposing world views - naturalism and theism. Naturalism opposes supernaturalism and insists that the natural world exists without incursion from outside, or as Carl Sagan put it: "The cosmos is all there is, or was, or ever shall be." The theistic view finds expression in the opening words of Genesis: "In the beginning God created the heavens and the earth." Theism understands the universe not to be a closed system, but a creation, initiated and maintained by God.The Genesis statement is a statement of belief, not a statement of science. This is precisely the case with Sagan's assertion as well. He is expressing a personal belief that emanates from a world view, rather than science."
