We base our entire lives off of partial knowledge on every topic of life. From the sciences, to history, to politics, and even to relationships. No one has full knowledge of any given topic. We exercise faith in every aspect of our daily lives whether we're conscious of it or not, and not talking in an exclusively religious context. To say that one must have an absolute degree of certainty or else the claim is false is absurd and irrational.
