No, Faith, science requires no presuppositions. It requires positions, positions which can be tested. That is all. If a concept, assertion, hypothosis or theory is testable, it is science. If not, it is something else.
Can you propose a way in which the assertion that god wrote the bible can be tested? If you can, then you can turn science on its ear. If you can't, then let's let science be science and let philosophy be philosophy.
There's nothing wrong with a philosophical discussion, be it concerning religion, art or anything else that isn't scientifically testable. The problem starts when you attempt to force science to take philosophy into account. It can't, or it ceases to be science.
