Advanced Extraterrestrial Intelligence

Consider three conjectures:
  1. The universe is the same age for all objects within it.
  2. Chemical reactions between two chemicals takes the same amount of time on Earth as they do on any other potentially habitable planet. (Corollary: physics is the same on all habitable planets)
  3. Human intelligence on Earth evolved as fast as the underlying chemistry could support it.
If those conjectures are true, then I would hypothesize that any other habitable planets with intelligent life contain an intelligence that is pretty much equal to ours. This would be a reasonable explanation for why we haven't (yet) seen evidence of extraterrestrial intelligent life.

Conversely, if their intelligence is far more advanced, then we would have to question what happened during our development to stunt our growth.
