Hee hee hee hee!!
I can just see them attempting that with me...
Witness: "So, have you ever considered this scripture at [insert appropriate scripture from the "Bible Teach" book or other Watchtower study aid...]??"
Zid: "Actually, I'd rather start out towards the beginning of that book - lemme see your bible... Let's start out with Genesis 1: 1-20, shall we? Now, would you say that the bible is scientifically accurate, being the "word of god" who - according to the bible - 'made' the earth and heavens?"
Witness: "Of course it is! Jehovah is our Grand Creator ™, and the greatest scientist ever!"
Zid: "Oh, really? Then can you explain to me, how "light" came to be - AND an "evening and morning - the first day..." - WITHOUT THE SUN??"
Witness: "Huh? Uh, well, Jehovah... Uhm.... Well, he split the darkness of the watery deep..."
Zid: "Oh, really? How is it, then, that the first form that the earth ACTUALLY took, wasn't "watery deep", but was MOLTEN ROCK, instead? How did your 'Jehovah' miss THAT little detail?"
Witness: "Huh? Uh, well, that stage must have come before the 'watery deep'... uhhhh...."
Zid: "And how does 'evening and morning' take place? Do you know?"
Witness: "Like the bible said, Jehovah separated the darkness..."
Zid - face/palming, by now...: "No, I mean, how does "evening and morning" occur, on earth, every day?"
Witness: "Well, the sun rises in the east in the morning, and sets in the west in the evening, and we humans call that a 'day'. But to Jehovah, a 'day' is as a thousand years, and man cannot know the mind of Jehovah, and....."
Zid is in full face/palm by now...: "NO! The sun APPEARS to 'rise' in the east and 'set' in the west, because the EARTH IS ROTATING FROM WEST TO EAST!!! And your 'jehovah' conveniently FORGOT TO PUT THAT INTO 'his' HOLY BOOK, didn't 'he'???"
Hee hee hee hee!!
