A very good comment on those assumptions. One only has to look at our own planet and ask it what way is it 'Optimal' for human life? To me, optimal would be the ability for me to walk around in a pair of shorts on any square inch of this planet and not worry about the environment get to me. I don't think I'd Last long in the Sahara or the Antarctic in just my skivvies....ergo, Earth is not optimal for humans. It is most likely good, but not optimal... (Well, maybe Hawaii is!!!!)
