if (according to the bible) adam and eve were the first people on earth, then supposing they had a boy and a girl, that would mean to continue the human race incest would have to have happend right? That seems a bit odd for a religion to say how the human race was started doesnt it?
So could I assume that you would believe in the existence of albino assassin monks for protection of the secret, the propensity for nocturnal basement sexual rituals for the continuance of the �royal bloodline� and that the �royal� bloodline still exists today? Or are you just picking the bits from Dan Brown that you might believe are true?
As I said, I am not saying that what I wrote is right, just a possible answer to the original question. Is it possible to answer a biblical queation outside of biblical context?
