It is ruled by law of nature, where the law is from is up to debate, scientists believe it is the way our universe is, which means it could be and will be different in other universes. Everything goes by this law in this universe, and there is no right or wrong in this regard. The nature is always changing but the law is not. If you understand the law then you understand the nature, believing in Nature? What a fool! Now realized Nature is not to be believed? Still a fool(to have this kind of thought)!
