What I meant was....
I just think it is amazing that we can survive w/o gravity... we didnt evolve with micrometeorites etc....I think it is interesting that of all the millions of steps evolution took, none of them led to gravity dependance... I am not claiming we are "the chosen ones" but I think it is a valid question..."Why do we not need gravity?"
There may be a simple explanation, but I havent seen it yet....
