WTC is making a concerted effort to erase their history of false prophesies but it is a fool's errand. There are simply too many ways to show the redactions. They were quick to discredit Ray Franz and it was all hands on deck. A district overseer told me that Ray was sporting a clerical collar and forming a new church. Of course there was no truth in that at all. The D.O. never apologized for the lie/misinformation - I think he wanted it to be true.
As for the 6,000 years of man's history ending in 1975, the achaeological evidence of civilizations dating back to 12,000 old is overwhelming. Because it is impossible to discredit, WTC does not even try to explain the discrepancy, simply saying that carbon dating is inaccurate. (In fact, carbon dating is often inaccurate as it typically underestimates the age of the artifact.
Nevertheless, WTC proves that it has no focus on truth whatsoever. If you want to see if they are lying, watch their lips to see if they are moving.
