The Big Bang only really accounts for our 'current' universe.

Then you and I may be in agreement that the universe didn't begin with the Big Bang. There was definetely something there before the 'current universe'. But then, shouldn't everything that ever was, including time and the current and previous iterations and versions of the universe be called 'the universe'?

I think we can only view one universe at a time, as, as I understand it, a different universe can have different laws of physics. I don’t claim to be an expert on this though, so take what I view with a pinch of salt.

Still, I guess there’d be more credence to the idea of big bang followed by big crunch followed by big bang, etc, if our current universe looked like it was heading for a big crunch. That is no longer the view, so beats me what was going on before the big bang. As someone else says, time started with the big bang, so the whole subject starts to give me a headache at this point :o)
