We can't be too hard on God. It's what happens when you try and take something as wondrous and complex as the human body from concept to market in a single day. You might forget that we'll need identical thumb prints so we can unlock our iPhones with both hands. That Appendix thing? Yeah no need for that cheers. Oh and why haven't we got a built in moisturiser for our face? Oh we have? Sorry, yes of course, as you were God.
