You cannot extrapolate what pre-BigBang conditions were based on post-BigBang conditions
You cannot extrapolate that an environment outside of our spacetime.
We can't tell what is outside of our existing spacetime, what the conditions are, the physical rules.
you can assert that, but you have not provided any proof, either logical, mathematical or physical.
EP,
then we must agree that, since you don't have any empirical knowledge of the conditions before (or outside) the Big Bang, your speculation is as good as mine. But at least I can speculate based on empirical rules observed on the present time-space. To deny infinity based on time and space rules that are yet to be observed is ultra-speculative.
But hey ... that's just ole me saying ....
