make yourself: Would you elaborate on what was said at your meeting that caused you to take notice of the "6,000" years of man's existence? Was it a comment? How old was the person who commented? Etc.. Please feel free to hold back any details that would reveal to much information .
Other post here have pointed out the background of this teaching. Let me add that the Photo Drama of Creation has a slide that presents each creative day as 7,000 years long. For Watchtower writers to "come clean" that the publications have been in error before and after 1919 would shake core beliefs about the Faithful and Discreet Slave. How could "God's sole channel of comunication" be wrong about the creation of the earth, etc.?
I remember when the Catholic Church (and others) dealt with this type of contradiction between science and the Bible. Things like saying that the first 5 books of Genesis are myths and not to be taken literal. The Watchtower responded by chargeing those religions with having no respect for the Bible. In Watchtower reasoning the fact that the "slave" respected the Bible, made them the true religion. Science makes progress. Evidence builds up. The watchtower's position is forced to change.
The question is: "how long will it take for the publication to directly state that Russel, Rutherford, Knorr, Franz, G.B. were all wrong about this matter?
Recent waffling on the length of the creative days (actually from 1987 to now), I suspect is due to this subject being a threat to the F&Ds credability.
