If we are talking about an exact match for Earth. MY point was "Earth like" - then the probabilities are wide open. In addition, I do not agree with your statement - each development of a planet is a seperate event and therefore infinitely possible. They are not joined. But if this was easy I would of won the lotto several times over!

That's okay if you want to disagree, but this is how odds are calculated. Besides, nothing, except perhaps the existence of the universe as a whole, is a "seperate" event. Besides, separation of events and their possibility of occurring have no relationship. You may as well say that since your eating sushi and my eating sushi are separate events each is "infinitely possible". But there's no possibility of my eating sushi and it has nothing to do with its degree of separation from your eating it.
