Taking current knowledge conventional theory in biology and cosmology as starting points:

  1. Chemical-based life can't evolve until you have enough supernovae to produce planets with a decent abundance of heavy elements. That means no life until maybe 5 -6 billion years ago, right?
  2. Life appears easily, but it takes billions of years to get beyond the microbe stage. Worlds with a 5-6 billion year history and no multicellular life could easily be the norm.
  3. We have no basis for determining how fast evolution occurred on Earth vs. other worlds - there are pretty good arguments for the view that we live in a very accelerated environment that would be very rare.
  4. If light speed limits are real, all we are really assuming is that we are not in the light cone of another Singularity. Given the above points, that is only a few hundred million light years - a small fraction of the universe.
