Is the Cosmic Microwave Background a Huge Mistake? [ At some point the the starry eyed high priests of the Big Bang sort of " jumped the shark " ]

As a non-scientist but science literate I am sure that advanced technology all around me , the wonders of modern medicine , are solid PROOF that -WITHIN ITS BOUNDARIES - SCIENCE gets the universe right . Until it crosses over into a type of Metaphysics in which Catholic Theology still shows some centuries old INSIGHT . At some point the starry eyed high priests of the Big Bang sort of " jumped the shark " . Did astrophysicist Fred Hoyle get it right ? Perhaps H.P. Lovecraft's " COSMIC HORROR " comes closer to existential TRUTH ? “The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.” ― H.P. Lovecraft
