I am aware of the scientific view that it doesn’t even make sense to consider time before the Big Bang, because time started with the Big Bang. And I am aware of the religious counterpoint, that God existed outside of time and created time along with the Universe.
There is a way that time began before our big bang.
Suppose that an intelligence evolves/rises to such an extent that he is able to to start a bb and create a new universe from within his own, he would then be in his own spacetime and outside of the new spacetime that he had created.
If the destined end of our universe is stagnation, then an intelligence might attempt to put the fizz back in the bottle.
