I imagine this very question, 'does the organization still say Adam was created in 4026 BCE?) that I asked my JW daughter was considered 'persecution' and 'spiritual endangerment' back when I asked it. I got labeled an apostate and shunned for that and similar questions. You should have seen the 'deer in the headlights' look I got. I don't think she even knew that was the official teaching.
This subject has got to be one of the most uncomfortable subjects for a lot of Christians since if one considers it in a logical way, it effectively nullifies the whole original sin idea and the very NEED for Christ. i'll take the Buddha over the sacrificial lamb any old day. Human sacrifice! How much more barbaric does it get?
