Exactly. And the endpoint of humans having evolved was only one of an infinite number of possible outcomes that MIGHT have happened form the process of non-directed evolution.<quoted text>
False analogy, Gilette.
The one CO2 molecule you picked was random, and there was a statistical certainty that a random molecule of CO2 would be picked.
It is a statistical certainty that evolution, once it began, would have led SOMEWHERE, but we cannot calculate the probability that it would have led to US, because that wasn't the goal and because we don't know all the various factors along the way.
