Why We Aren’t All Smelling Our Butts Right Now

Question from Blink:
Hi guys. A theist asked me this question.

“Why are our eyes (not the anus) placed near our nose? Can you imagine how disturbing it would be if it were placed below our nose in place of our mouth!”

This is one of the many reasons why he believes in God.

I don’t know how to respond to this question, my instinct tells me maybe it has something to do with evolution. What is the appropriate respond to his question? Thanks.

Answer by SmartLX:
The anus is placed away from the mouth and nose because if any of our ancestors had developed the two close together, the species would have quickly been wiped out by anal-oral and anal-respiratory infections. On the other hand, the anus is placed near the genitalia and there’s a constant risk of infection between the two because that kind of infection isn’t usually enough to cause a major obstacle to survival, and there hasn’t been any major selection pressure to change it.

To make the same point more generally, if something being the case confers some kind of survival advantage, or if the alternative would make survival difficult, evolution is likely to encourage it to happen, because life will be easier at every stage for those who are closer to the ideal. Bad “ideas” are weeded out when the life forms that manifest them die.

But forget about evolution for a minute. Your theist asks why a particular thing is the case, and implies that if you don’t know, God must have done it. How utterly arrogant to think that just because the two of you may not be aware of any other explanations, reality must align perfectly with what HE thinks. This is a classic argument from ignorance, and the more people know what that is, the better for logic and reason in the world.
