It is interesting how much the WTS stresses the scientific references that they have, and talk about thoroughly researched...blah, blah, blah, blah.....They have a way of presenting their research in such a manner that no "good" JW would dare look up the references and refute them.
They pick and choose what they want of course, like most do when adding footnotes to articles or research. Sometimes they get so caught up in trying to look scientific that they forget that common sense should prevail.
Remember the big blue Creation book that came out in the late 80s? I absolutely loved this book when I was a teenager...I placed one with my biology teacher in 10th grade. To read it as an adult though, I think a first year college student of even a well read high school senior could write better material.
Just because someone has a scientific degree doesn't mean they any more common sense. It sounds like this scientist has allowed his scientific interest to be soooo narrow that he wouldn't understand any scientific proof that would seem to disagree with the bible.
As for me, scientific proof would mean nothing, since I don't think the bible is inspired of god, but written by men who were just inspired to look at their everyday lives and try to put an extraordinary spin on the events happening to them.
