Strictly speaking, modern cosmology does not treat the Big Bang as the beginning of all of existence, it's what happens when you take observations about large scale cosmology and run them backwards in time.
Based on the information we have available about our universe, we can't make predictions or formally model anything prior to a certain point in time, consequently it's convenient to treat this moment as the earliest point in time in which physics as we know it makes any sense. So while there may have been some kind of existence prior to the Big Bang, we have no way to make sense of it even at a conceptual level. Given that, we may as well treat this special point in time as the beginning of the universe as we understand it and can explain it using physics, as opposed to some absolute beginning of all of existence.
We don't. There was never nothing, because there is no "before" the big bang. Time as we know it did not exist until the big bang. It's not there was nothing, it's that there was no there or then.
There is as yet no proof that there was nothing before the big bang, it's just a supposition. The hot dense universe definitely happened but whether that was the "beginning" is essentially unknown.
"beginning" is a misnomer, since time itself started with the Big Bang. There is no such thing as "before" the singularity, as time and space were curved together.
We don't need it, the same way we don't "need" scientific proof about anything. We could live our whole life pleasing the stakeholders and be happy about it
Only if something exists. But both nothing and something could not exist, and then there is no duality, just nothingness without a something to relate it too.
There is no proof of "nothing " existing. Every observation we take, we see "something".
Than why do we need a beginning if there was always something.

My lay interpretation of this theory is that it says there was no beginning.
But a cycling of a previous universe.
I was a little unclear on the ending, where he says this theory would place our entire universe "inside" a black hole of a parent universe.
All in all, it does seem to tie up some loose ends, and suggest some order to what previously required speculation.

For the same reason the mind seeks for an ending if there is something. It’s the environment our little neural nets trained in.
Only if something exists. But both nothing and something could not exist, and then there is no duality, just nothingness without a something to relate it too.
The concept of Nothing can only exist if Something exists, they both exist and are the substance that make up the universe.
That’s a boring axiom.
Nothing is everything
Everything is everything
