If there' are essentially infinite parallel universes, then a case where probability of abiogenesis is so rare (to the point that zero life in this universe could have occurred) is a possibility. There is also the problem of the Great Filter. Life could form commonly, but intelligent life could be rare from a bottleneck somewhere in the evolutionary process. The filter could also be in the future, which I'm certain there is one. It's getting easier and easier for a sole actor to be destructive. There are many potential theoretical technologies and issues coming ahead that could wipe out civilization.
My greatest fear is a self-aware AI, any sane AI would wipe us out within 20 minutes of becoming self-aware. It would come to the same conclusion that Agent Smith did in the Matrix, that we are a virus and need to be eradicated.
