Dating Methodology and its Associated Assumptions

WT: Pay attention, class, and I will demonstrate how easy it is to demolish the lies spread by evil scientists.
WT: You see before you ten glasses filled with ordinary water. Those Bible-hating ‘scientists’ will tell you water is composed of hydrogen and oxygen, but what do we find when we analyse the contents of these glasses? Using evil laboratory techniques, of course. Let them hang themselves with their own methods.
WT: Nine of these glasses have water composed of hydrogen and oxygen, BUT, notice the analysis of the tenth glass. Hydrogen! Oxygen! Fluorine! Chlorine! This conclusively proves the theory of the composition of water is a lie. Science is a lie. If God wanted us to know the composition of water, he would have instructed us through his spokesmen, Abraham. Or Elijah. Or even Jesus. But we find no evidence for water`s formula. So it will remain a secret till the End Times, when mysteries will be revealed.
