What is it that implies that the Big Bang created a universe as opposed to a big bang in an already existing universe?

PBS Space Time explains some ideas, pretty well founded in the physics of what we can detect and derive Before the Big Bang

Nothing. The Big Bang explains features of the "observable universe", like the cosmic background radiation and the original elemental abundances. It says nothing about what what is beyond our range of observation.
If there were an already existing universe within our range of observation, we would expect to see stars older than the ones we see. The age of the ones we see max out at a bit after the Big Bang.

Nothing. There is no way for us to know what was befote the big bang as of yet.
So its "the beginning"
Just how they have an age in the universe. That is the age because that is what data told us. When we got ol james up there, we had begger data and the age 'increased'
