If 6 billion individuals were sourced out of this mythical Adam and Eve, all of these inbreds would be dropping like flies in a rainfall of pesticide, due to genetic abnormalities accumulating over the generations.
Yes, there is a large and sad contingent on fr that truly believe that we are all decended from ‘devine inbreeding/linebreeding’ - and that Darwin was the original antichrist.
You seem to be thinking in current terms as genetic defects are rife today and inbreeding leads to deleterious genes. The gene pool started out perfect with the addition of the death factor after Adam sinned. The faults have increased slowly over time but the curve seems to be somewhat of an exponential one. People in general are becoming very polluted with genetic faults. At this rate we may not have much time save The LORD’s eminent return. Another good reason to say “Come LORD Jesus”.
