Are there any theories of what happened before the Big Bang? Are there alternate theories to the Big Bang?

There are alternate hypotheses to the big bang, but the big bang is currently the only accepted theory.
As for before the big bang, there’s no way to really know, since it is thought that spacetime started then.
There is the big bounce hypotheses: https://en.m.wikipedia.org/wiki/Big_Bounce
Which is the only one I could remember off the top of my head.
