Catholic Bible - extra books?

Hi, what about the extra books in the Catholic bible that is not found in the Protestant Bible?  How can we understand / trust the canonization process when there are such differences?  Can you comment on this?

Fine-Tuning Argument: Combinations of Constants?

The fine-tuning argument relies on the idea that all these different constants line up so perfectly to make the universe viable.  But how can we make this kind of probabilistic conclusion because we don't know how other possible combinations of these constants might have worked.  For example, maybe even if the universal gravitational constant were too low, if the expansion rate of the universe is also lowered appropriately, then things might have worked out.  And since we don't know how many other combinations out there are viable, we can't say that our current universe is particularly amazing or improbable.
