The whole scientific enterprise is based on certain assumptions which cannot be proved scientifically, but which are guaranteed by the Christian world view; for example: the laws of logic, the orderly nature of the external world, the reliability of our cognitive faculties in knowing the world, and the objectivity of the moral values used in science. I want to emphasize that science could not even exist without these assumptions, and yet these assumptions cannot be proved scientifically. They are philosophical assumptions which, interestingly, are part and parcel of a Christian world view. Thus, religion is relevant to science in that it can furnish a conceptual framework in which science can exist. More than that, the Christian religion historically did furnish the conceptual framework in which modern science was born and nurtured.  —William Lane Craig (from, What is the Relation between Science and Religion)
