I think SLIMBOYFAT was onto something when he wrote this " According to the Genesis account Adam was 130 when they had their first child, so that sets the absolute limit of the delay between the creation of Adam and Eve at 129 years. That would put the latest date for the 6000-year anniversary of the creation of Eve at 2104. That would be 190 years after the Gentile Times ended in 1914 – quite a stretch. "
Now what I am looking at is to take this a bit further ,Slim's notes point to a possible armaggedon by the latest in 2104.
Now think about that 129 year delay between Adam & Eve being created ,remembering that FRANZ would spend some time with a Jewish man who was scholarly but who was not a JW and apparently they discussed the scriptures together.
Think who was seen as the WTS guru ,Franz, and who pushed for the possibility of 1975 as the end! Franz .
Now look at Slims figure of 129 years since Adam and Eve became a couple leading to year 2104.
Now take that year 2104 and deduct that 129 years ,2104 - 129 = what? Yes the year 1975,.
Maybe Franz worked out the watchtower prophecy this way ,errr but what then happened in 1975 -nothing but a zero.
I did my first study with an elder named Adrian in the 74 to 75 period and I know well what he was expecting in 1975 and he was not the only one. My future mother in law pointed out the scripture "no body knows the day or hour" ,so she did'nt put too much hope in 1975 ,but it was enough for me to stop my first study.
