    the cosmic microwave background radiation temperature is 2.725K which sets a limit for the energy density of the early universe which in turn sets a limit to the number of possible planets etc. for aliens to evolve on

    and let's not forget that you need supernova to create metals so only second generation stars could possibly support life as we know it.

    even the brightest of the dinosaurs had tiny brains compared to birds and mammals today and that on a tectonically active planet with large tides and variable seasons due to orbital tilt, not to mention all the good stuff having a moon does, means that the chances of intelligent life evolving on another planet by now aren't great
