Why does there have to be time before The Big Bang? IIUC, the hypothesis is that everything was packed into one super-dense black hole. Wouldn't there not be

  However, you play around with words the same question always remains what was before. Where did this super dense black hole come from? What caused it to be? What was it before it was a black hole? Our current theories for the origin of black holes as far as I know does not include the spontaneous appearance of a black hole for no reaosn.

What was it before it was a black hole? These theories are just that - thought experiments to try to come up with possible explanations. They are not claimed as proven or facts. There are a lot of open equestions. It is work in progress. > Our current theories for the origin of black holes as far as I know does not include the spontaneous appearance of a black hole for no reaosn. There are actually theories that black holes can form spontaneously. This is because particles are theorized to be able to spontaneously form and under the right circumstances they'd form a black hole. They would most likely though evaporate nearly instantly. But again that is not proven.
