Before the 'big bang' the most fundamental unit already existed, only in a different 'form' with different dimensions. The big bang was just a change really. This might sound kicking the can down the road-ish but it's what it is. There's no possible explanation on how something so basic as e.g. strings and branes can come into being. It's better if you accept that there's a basic unit to our reality that which is eternal. So the only meaningful question is the 'why' and 'how' these basic units transformed into the universe as we know it. And that's why the 'big bang' hypothesis makes much more sense than trying to guess 'what was before the big bang'. It's unknowable, it's ununderstandable and at the end of the day, it is irrelevant. It's basically just philosophywanking at that point.
