"How can we predict what God is going to create next? At least with evolution, we can use it to predict what can happen next with the avian flu, for example, that it might evolve to be transferable between humans. If we used intelligent design to predict what could happen next, what would be be able to predict? That it might one day turn into a cantaloupe?"
That is the problem with evolution. You can not predict what happens next and that is exactly what real science requires. You have your argument backwards. AND the process needs to be repeatable.
So what is your pet dog going to turn into next? Evolution if it is indeed a fact should be able to tell you.
