The real problem with life forming is not a "habitable zone" but rather the question of abiogenesis.
How likely is it that a self replicating molecule would form at random? Well really, we don't know anything about that. Many estimate the odds to be so low that it wouldn't happen in the Universe anywhere ever. So either there is some sort of self organization that makes the whole process a lot more likely than chance would dictate or else it truly is a damned miracle, the luckiest of all lucky events and again - maybe we are the only ones then.
