So there's a question about whether people "believe" in cabin dating? I understand the WT has tried to shed some doubt on the process, in an attempt to show that history doesn't prove the bible to be inaccurate.. But he was the one who was surprised YOU believed in it? Never heard that one before.
I like your line of questioning. It could be adapted for a fader or "in" person to get someone to think. Some JWs like to try to prove that JWism aligns with the facts. These are great questions for those people.
well done
