And BTW, I didn't say that Laplace did not believe in a god, only that he didn't need a supernatural explanation in his works. And the same is true for many scientist after him.
No scientific field is free from religious presupposition. Naturalism permeates all of them (geologic column is naturalistic in its assumptions; evolutionary biology assumes spontaneous generation and a professor at the secular university I attended even wrote in the school paper that Miller's experiment proved life could spontaneously generate - a lie; naturalistic physcisists teach that the universe suddenly sprang into existence from nothing; we have JW Gould, now a theist, who said that people were no more significant in this cosmos than a "dried twig" - no religious assumption there!).
On the other side, in chemistry, we have W. Dembski and ID theory which is theistic in its assumptions, etc. I can cite examples till I'm blue in the face. How many will convince you? In short, yes, no field is exempt from religious presupposition. They ALL have the underlying belief about God's existence.
Name a version of the origins that is not either theistic or atheistic in its implication. Good luck.
