No, the 'laws of physics' don't bring things into existence. A physical law is a statement, usually mathematical, which describes some aspect of the physical universe. For instance, Boyle's Law (PV = k) describes the behaviour of gasses with regard to pressure and volume, but it doesn't cause helium to spring into existence.
