That's a bizarre opinion. You need to ask questions to which you don't know the answer to discover anything.
Re-read what was posted and think about it.
Take your first post above. In science you were taught the hypothesis and null hypothesis. These are small steps, simple questions that can be answered true of false. Science is the search for what is false; you are left with the truth.
Asking what came before the universe can't be answered - it is not a good question. It may be nothing, emptiness. Yours guess is as good as the next person because it can't be answered.
It is like your girlfriend accusing you of looking at another girls boobs. How do you prove you were not. It is un-falsifiable.
Does that explain what I mean better?
