Scientific method is founded in ‘thinking critically, as opposed to accepting what you are taught blindly’. Science is essentially epistemological, it is not conventional or common to use scientific method to approach ontological questions: not least, these issues can seldom be formulated into an empirically testable hypothesis.

For all that you function in a scientific role, you seem to share something of popular ignorance as to the (formal) philosophy of science, and might find it interesting to explore the psychology of belief.
