I am not sure what Buzsaw was meaning in his statement, and he is not around for the moment, so I will twist the argument for my purposes. Taking the statement as it is, it only says that the probability of atomic particles organizing by themselves to produce the universe, and all its content, including life as we know, is less than the probability for the Bible creation description to be true. He is not saying how high this probability is!
I personally think that the probability increases, as we diminish the literalism.
