Funny. They can't explain it so they say it didn't happen.
Yes, the Big Bang really did happen. And there really was something called Singularity.
No, it was not the beginning of existence because all potential of the present universe existed within Singularity.
I give the quantum people credit for trying to explain everything but it seems to me they imagine answers to questions they can't answer with facts.
But we exist now and I think that is important.
