I only used maths to demonstrate that there are many areas (not limited to maths) where one answer is held to be correct to the exclusion of all others...I did not intend for it to be entirely analogous to the basis of religious belief...because maths, rather uniquely, can use its own internal rules of logic to prove further rules of logic...however, that said, even maths is dependent on holding to fundamental, unprovable axioms. Furthermore, most of our lives is lived outside of a realm of rigorous proof: you can't prove that your mother loves you (in the same way that you can prove a mathematical theorem - you can only draw conclusions on the basis of past experiences), you can't prove what your favourite music is etc...in fact most of our daily actions are informed by our past experience, rather than by following some rigorous mathematical-style proof or logic....and basing future actions on past experience is a form of faith!
