Those rely on linguistics only, no empirical proof, like axiomas in mathematics.
It is impossible to explain the origin of the material world from the material world. The origin of the universe is out of the universe. only the philosophy and metaphysics can explain this, is a logical answer. you don't expect that mathematics can resolve all questions, with an equation, because this is out of mathematics scope. This is like trying to resolve a physical problem with philosophy. it doesn't make sense.
