Jwoods the fact that bible literalists dismiss archeological evidence if it doesn't conform to their world view would indicate they are interested in the search for truth. "If ain't in the bible it must be from Satan, that is the attitude what really stifles human endeavour
There is a fundy true-Bible-believer here at work who actually thinks that God put the dinosaur fossils into the earth "as fossils originally" (no living dinosaurs really walked the earth) in an effort to "fool" unbelievers into going away from the true words of the bible.
For a long time, the JW world actually believed that ALL CREATION on the earth was done in about 49,000 years, most of it being done in the early part of those 7 x 7,000 year old "creative days".
For the most part, though, it is useless to try to argue observational science to a bible literalist - they will go to any length to deny the physical record in favor of some bible notion of reality.
