Thank you for setting up this Side Comments thread, Joshua.
I have perused your paper but not fully digested it. I appreciate the work you have done. I see the value of rigorous science. I also see value in pointing out that Adam and Eve could have lived as recently as 6,000-10,000 years ago.
But does such a late date fit other scientific evidence and Biblical or theological requirements?
For example, it is important that Noah and his family be the only humans who survived the flood. Theologically, this flood might be regional as long as Noah and his family were the only survivors.
I’m not an expert in geology, but I just did a quick check and see that about 7,500 years ago there was a massive Black Sea flood. Is there any reason that the human population could not have been reduced to just eight persons around that time?
