Science is naturally skeptical, as this forms the basis of scrutiny, but should have a sufficiently open and curious mind to explore further. The purpose of science then is exploring ideas and the goal is to leave any state of doubt or ignorance behind through testing, and act of faith in itself, come to discover direct evidence, even proof, to advance and progress in understanding or equally to discover error of method or presumption.
The question is why the 'God idea' doesn't fit the same model. The answer is self evident. Theology and tradition have failed of offer anything that can be tested! So what has been revealed? Nothing. Theology only exists because nothing has been revealed. Of course anything which fit the model would also bring down all of monotheism as we know it. And that is what appears to be happening right now!
The first wholly new interpretation for two thousand years of the moral teachings of Christ is published on the web. Radically different from anything else we know of from history, this new teaching is predicated upon a precise, predefined and predictable experience and called 'the first Resurrection' in the sense that the Resurrection of Jesus was intended to demonstrate Gods' willingness to real Himself and intervene directly into the natural world for those obedient to His will, paving the way for access, by faith, to the power of divine transcendence. Ultimate proof!
Thus 'faith' is the path, the search and discovery of this direct individual intervention into the natural world by omnipotent power to confirm divine will, Law, command and covenant, while "correcting human nature by a change in natural law, altering biology, consciousness and human ethical perception beyond all natural evolutionary boundaries." So like it or no, a new religious teaching, testable by faith, meeting all Enlightenment criteria of evidence based causation and definitive proof now exists. Nothing short of an intellectual, moral and religious revolution is getting under way. To test or not to test, that is the question? More info at
