It’s called ‘creation’. The Big Bang theory was proposed by a French catholic professor/cleric le maître.
Hubble proved him correct, in part, with his observations of the Hubble constant.
Latter scientific results have continued to confirm this theory that our universe was created from ‘nothing’ in an act of creation 13.8 billion years ago.

No. It confirms that there is motion in the observable volume of the Universe. Further, gravity waves only confirm Einstein’s general relativity theory.
Everything else is invention supported more by wishful thinking than reality. Like the old saw about the blind men describing an elephant. We know there’s legs, we know there’s a tail, but it could just as easily be a cat or a horse as it is an elephant.
