The question is what sort of singularity? Most physicists think of a singularity as a Robertson-Walker singularity, or a point of infinite mass-density.

There are three key points to notice here.

A Robertson-Walker singularity is readily avoidable, if the cosmos rotates, for example. The whole point of Hawking’s singularity theory was to try to show that a singularity (or a true beginning of time, or creation) is somehow inevitable.
