Looking at the bible narrative now, with open mind, the talking snake and all, it is a poorly contrived story. but
all these clever people picking up and adding to the thread, the fabric its intriguing, certainly a valued literary work. fiction.
Using this story WT has woven another, parallel account that you would expect to harmonize with it, and hopefully attempt to connect with reality.
In your thinking, where did WT become unhinged, drifted off into total detachment?
example: In 1918/19 WT announcing that within 6 years people would start never dying, come back from the dead. dead wrong.
from then on anything further was even wronger.
