Its not merely a convention, its a widely accepted idea that time did indeed begin with the big bang.

Its not a universally accepted idea, serious scientists disagree, but it is the majority opinion (even if other ideas are gaining on it).

Some would instead say that before the big bang there was a collapse of some previous universe (or depending on how you define universe, some previous incarnation of our universe), others support a conventional single big bang hypothesis, but think that why we can't describe time before the big bang that it existed in some way, others thing that colliding membranes created the big bang, but the membranes (and time) existed before.
