Whether you believe in Creation or evolution or intelligent design or not-so-intelligent design or whatever, the male scrotum surely has to be a mistake in all of them. To take the pouch that holds the seed of future generations and to leave it hanging outside the body, vulnerable to all manner of assault, just seems like a very bad choice in any doctrine.
Aesthetically, the scrotum even looks like a mistake; a bit that someone on the evolutionary production line was meant to tuck away to make the body look neater and more streamlined, but they fell asleep at the quality-control switch and by the time the error was noticed it was too late because the product was out in the marketplace.
In Creationary terms you'd have to hope that someone had some explaining to do on whichever day that particular part of the human anatomy was not very intelligently designed: "Hang on, what's that thing there? The wrinkly thing down there, between the legs." "Yeah, um, we were kinda hoping you wouldn't notice that, sir. That's the scrotum."
"But the male specs call for the scrotum to be nestled safely up inside the body, just behind the peeing and insemination device. It looks terrible there. And uncomfortable.
Won't it get crushed between the thighs, hanging down like that?" "Sorry. Bit of a cock-up, as it were. By the time we noticed the error it was too late to correct it, because the deadline day you set for the Adam model to be rolled out was just about on us. We tried to dress it up a bit in what time we had by whacking a few hairs on it, but looking at it again now we may have actually made things worse. Sorry again, sir." "Don't apologise to me. Apologise to the countless generations of males who will have to live with the fact their family jewels are just dangling there, vulnerable to all manner of assault. Man, when some poor bastard gets hit square on that thing with a fast-moving object or a knee, the pain is going to be eye-watering."
