There's one possibility that explains it: that the probability of a genetic code evolving naturally is really, really, really low. Like, less likely to happen than once per universe. Then, once this barrier is attained, other forms of evolution occur more readily. As we don't know the mechanisms for how it happens, it's a possibility. The anthropic principle allows for it, but it likely requires multiverse theory and/or infinite universes coming and going over time. There's just no consciousness in all the infinite universes where it never occurred, so there's no one there wondering why there's no life.
