Not to be unpleasant but this guy's no "law professor". In French un profeseur is merely a teacher. Ok he has a PhD, that May make him a Dr of Law, but not necessarily a professor. Where does this dude teach? It could be an adult education institute, the local community college as you Americans call it. Not putting anyone down who is a teacher, where ever they teach. Just saying. it's not beyond most people's Ken, given the time and money, to get a PhD. It certainly doesn't make him an "expert" in evolution.
But even a teacher at high school, teaching logic, would not make such a poor analogy ....effectively he used the old watchmaker on the heath and turned it into a bench in a forest. It's been utterly debunked by philosophers long ago. How can an expert in logic not know an undergrad example such as that.
I reckon he fell for one of his JW community college students ...and had to convert to marry her.well that's my story and I'm sticking to it!
