Belief/Faith in a creator/religious ideology is by definition a position based on no proof/evidence.
Faith-
2. strong belief in the doctrines of a religion, based on spiritual conviction rather than proof.
Then you have the laws of physics which can be believed because there is repeatable peer reviewed evidence available. Another example is the theory of evolution ie. evidence based and indisputable.
Evolution very likely did happen, however it is not "indisputable". By yourself labelling it a "theory", means it is actually very "disputable".
A better comparison would be "how did the universe start/form"?
