These are just a couple of arguments I think would cause any half sane JW (if any current and actively brainwashed "true believer" could ever be described as sane), to stop and think for themselves.
Thinking person: Is the bible and the events it describes true and factual?
JW: Yes.....to the letter.
Thinking person: Could evolution be true?
JW: No way.
Thinking person: Ok, so I just want to get this perfectly clear; evolution in no way happened, is happening, or possibly ever will happen? God created just two people in the form of Adam (a man) and Eve (a woman), presumably both of the same ethnic origin, and this happened roughly six thousand years ago?
JW: Precisely.
Thinking person: Ok, and then Adam & Eve proceeded to pro-create and gradually populate the earth. After much inbreeding and a few too close for comfort relationships between family members, they eventually got to a point 2000 years later where they had populated the local area and filled it with a disgusting collection of evil people whom god decreed he would have to kill by causing it to rain (heavily) and thus drown the lot of 'em. All except one small family who's father (or brother, or son, or all three depending on which way you looked at it) was called Noah. Noah and his close knit family were going to be spared and therefore given the responsibilty of starting the re-population process all over again from scratch. Have I got the basic idea of it?
JW: Yep, that's the way we see it.
Thinking person: Alright then. And this all happened just 4000 years ago by your calculations?
JW: Indeed
Thinking person: And I just want to confirm that evolution is in no way possible. Correct?
JW: Correct. Evolution is not possible. The bible clearly tells us that we were created and the bible is 100% factual and correct. I know it's 100% factual and correct because it tells me so.
Thinking person: Splendid. So can you explain how, in just four thousand years since Noah gingerly stepped out of the Ark on to the sodden ground bereft of any life forms, (because at this point the last two survivors of each species, every last one of them, was still crammed into the Ark), did one family, who I presume were all of the same ethnic origin, or at best two ethinic origins if God had the fore thought to create Adam & Eve as separate races, manage to populate the earth with the diversity that we see today? I mean how did we get from just one colour of skin and facial features to the great and wonderful variations that we see all over the planet? Black, White, Asian, Native Australians, Incas, Aztecs, Oriental and all the slight differences in between?
After all, evolution absolutely can not happen. We didn't evolve to different skin types. There wasn't a slow progression from one to the other to suit the needs of living in different part of the planet because that would be evolution......evolving to adapt to the environment, and the bible tells us that isn't true.
Now I'm not arguing with you on that point JW. I'm more than prepared to believe you and accept that we were created. I can buy that. But......and it's a big but as I'm sure you'll agree. If all the different races on the planet didn't evolve, the only alternative is they were all created. But the bible says that God only created two people; Adam and Eve.
So here's my argument. As I see it there are only two possibilities. Either all the different races of people evolved, in which case the bible's version of events is wrong. OR, all the different races were created, in which case the bible's version of events is still wrong. God would have had to create a male and female from each ethnic background, and keep at least a male and female from each race alive during the flood and after. Either way you look at it the bible's version of events is wrong. You see, you simply can't have it both ways.
So what do you say to that?
JW: Ugh, umm, argh. Listen I'm not going to sit here and listen to a trouble maker like you. I know I've got the truth and that's all I need to know. If you want to listen to the false teachings of the "world", that's up to you, but don't come around here trying to discourage others.
JW later that day whilst thinking to himself: He had a point you know, I'd never thought about it like that before. "Right stop thinking Bob, that's Satan getting into your head. Just listen to the old baffoons in Bethel, trust what they tell you without question and you'll be alright". Phew, seemed to crush that little rebellion........right, where's my Daily text from the scriptures?
Ok, I was going to write a second argument, but I think I've gone on enough for now. I'll come back tomorrow for the second one.
I hope this gives some food for thought and maybe some ammunition to hit them with next time they come a'knocking!
