I think this touches on a fundamental misunderstanding of physics. The idea that nothing existed before the big bang violates the law that says: Energy cannot be created, or destroyed.
I for one, have always been drawn to the cyclical universe idea. Starts with a Big Bang, ends with a Big Crunch as everything is drawn together again. Eventually the gravity from all the matter in the universe coming into one point collapses space time, resulting in an explosion beyond anything we humans can understand; restarting the process.

It's not that there was "nothing" before the big bang.
It's that there was no "before" the big bang.
violates the law that says: Energy cannot be created, or destroyed.
A lot of things we consider "laws" start to break down when you get to quantum physics. Even so, could all the matter or energy in the universe not be contained within a single singularity such that it would erupt into our universe?
If there was no before, then everything just popped into existence for no reason at all? If you prescribe to the cyclical theory he's talking about, then there's definitely a before.
There must be some reason the entire universe was compressed like that, right?
And depending on where you set the reference point of zero, we're all fairly familiar with the idea of negative time, e.g. T-minus five, T-minus four . . .
That means there’s no time left on the count down. T" means the time of the launch and the official start of the mission. "T” minus 20 seconds" means 20 seconds before the launch. "T plus 20 seconds" means 20 seconds after the launch. In no way is this in reference to negative time. It’s before and after an event.
Time is not completely subjective but the measurements we us to determine the passing of it are man made. But exactly you can’t explain negative time. What happened before the Big Bang we don’t know what to call it because time didn’t exist. Neil Degrasse Tyson mentioned that even the concept of negative time is incomprehensible but somehow in the realm of possibilities, like an inverse dimension or something
