As was just quoted in another thread here:
It’s exceptionally unlikely that you are going to be able to use logic, reason, or facts to argue with someone who is, as you say, using the Bible as a scientific manual. You aren’t really bursting their bubbles, because in their minds, you’re the one who doesn’t have the facts right.
Unless you really really enjoy fruitless debates, or arguing with people who will never be convinced, it’s simply not worth your time.
(And, yeah, when I was younger, politics and religion were the two things that you didn’t bring up in polite social company. Both of those have gone out the window now.)
