What manner was that? How was the CMB produced exactly?
Because I know how it was produced and I don't see how it could be produced in the same manner. So please tell me how it was produced in the same manner.
You do realize that you just said black holes existed before the big bang, right? There are two problems with that. How can black holes exist before the big bang and if the universe had no beginning, how was there a big bang at all?
Then it sounds like you need to go read up. Google Penrose.
You are dodging the questions, dummy, because you don't know why the CMB exists. If you knew why the CMB exists, then you would understand why the universe began.
But you don't, so you post anything from a google search that looks like the universe may not have begun. Unfortunately for you, the CMB is the fingerprint of a universe that was created from nothing. It's the smoking gun. It's the evidence that the universe began.
