An interesting question relating the argument from evil to evolution. This is a common argument against forms of theism that accept at least large chunks of evolutionary biology:
Using an evolutionary process over a long time, as opposed to custom-creating everything in six days, seems to leave us with a world that has a lot of suffering in it that would not have otherwise have been there.
Further, one of the reasons that is most frequently offered for believing in evolution is that we have various features that are less than optimal. Our backs tend to hurt because standing straight is a relatively new development in our evolution, and somewhat unnatural. But if God had custom-made us, he would have given us stronger backs that don't get sore so easily. Why didn't God do that?
What is the best theistic response to this objection?
