Just to perhaps correct the relativity on this point. For those that believe, god, allah, whatever doesn't make mistakes, how do you actually prove that statement?
I tend to believe this is yet another of the plethora of urban myths, promulgated to support profoundly unproven and unprovable myths or creationist theories, also sometimes referred to as,"faith;" by organisations wanting to control a segment of society, if not all.
May I further offer a well worn christian belief and perspective that is supported in biblical text, that since Adam fell from grace with god, we are no longer prefect, and made to toil by the sweat of our brow, and a whole heap of other travesties not considered worthy in the original manufactures production brief. This belief should therefore automatically extend to the understanding we are now prone to being mistakes. Gives traction to the story of the second coming so we can be "redeemed" (hopefully not for an additional 500 mile leg with United Air

) and made perfect again. I believe that story had that particular event happening in the "twinkle of an eye", or words to that effect.
So until someone can provide reasonable, sustainable proof that the creator doesn't make mistakes, I'll have to continue to ignore peoples belief in that theorem. As my understanding is we are all mistakes, in one way or another. (OK you load of perfectionist up there in the bleachers, sit down and shut up

)
So; a baby born with spina bifada is not a mistake. Hummmmmmm. So, what do
you call it? I'm open to your theory, it's your turn now.

P.S. May I offer my apologies to those that may take offence in my deliberate no capitalisation of some proper nouns herein. It's my belief, respect has to be earned. It's not an automatic qualification deemed by the use of a particular set of proper nouns.
