Like with everything thing else Blondie , the Watchtower was wrong. A recent serious attempt at arriving at the total number of humans who have ever lived is something like 110,000,000,000-- one hundred and ten billion. I guess this is just for Homo sapiens but since humans evolved we were breeding with Neanderthals and Denisovans (amongst others) during our 300,000 year history. So should we not include those other members of our genus (Homo) as well since we are their offspring?
A proper evaluation of what humanity is makes nonsense of the Biblical claims and demonstrates that the Bible was simply myth told in the absence of a scientific understanding of life.
The idea of cheating death is an understandable wish and is the reason for the presence of religion in most human cultures. But which is the more absurd: never dying or resurrecting billions and billions of the dead?
