I agree with you that those are indeed life sustaining factors, but my point still applies to each of your individual observations: with only one universe, how can you assess the probability of the particular chain of events leading up to its current state taking place? We only have one universe to examine, and therefore how can we know what the chances are of a universe coming about that contains a planet coming about with a gravity of 9.8 m/s2? How can we know the probability of a universe coming about that has this distance from the sun? Or oceans or an axial tilt or etc? Like I said before, without several universes to examine, there's no way to assess the likelihood of such conditions coming about.
I think this will make this concept easier to grasp. Suppose you're given a bag containing a bunch of marbles of various colors. Then suppose you pull a marble out of the bag and it turns out to be blue. How can you know what the probability of pulling out a blue marble, if that's the only marble you picked? Was there a 1 in 10 chance? Was there a 1 in 5000 chance? Were all the marbles blue? You won't know unless you take out more marbles.
So I'd just like to ask, how are you assessing the probability of events for which we only have one example? I.e. what are your calculations that made you arrive at your million billion trillion etc. figure?
