Perhaps it has to be this way, just as the decay of matter gives birth to new life, so to do black holes give birth to new universes. What seems improbable is the way of things.
Then why are the conditions for life to form so difficult to come by? With Trillions and trillions of black holes in our universe, wouldn't life be more common if their purpose was to create new life?
Douglas Adams had a great analogy for this fine tuning arguement.
"Imagine a puddle waking up one morning and thinking, "This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn't it? In fact it fits me staggeringly well, may have been made to have me in it!" This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it's still frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise."
