I need help. I guess I got in over my head on this one. But also, you guys said it's a good learning experience, so you're teaching me. And in turn I'm teaching him, lol. Thanks for all of your help.
Here is the problem.... it's not that you are in over your head... it's that you are trying to explain calculus to someone who never got past addition.
Unfortunately, one often has to resort to analogies and metaphors to teach these kind of people about more advanced concepts.
I have never met anyone (online, in person, etc) who understands evolution and still doesn't accept it.
You will find that close to 100% of the people who don't accept evolution simply don't understand it. (and often they don't understand much of the more basic biology underlyling the theory either).
