I'd go as far as to offer an explanation like this: The universe/multiverse is infinite in every (by our brains) comprehensible and incomprehensible form. Both on a macro and a micro level. Our existence is finite in nature, both in space dimension (objects have edges) and time (they change form). It is understandable we have trouble interpreting some of the rules of our universe that we are unable to comprehend. I say quantum mechanics (and perhaps natural science in general) are our attempt to make sense of something fundamentally not comprehensible.
