Which biblical chronology is most correct, and how do you date Adam?

You cannot start from Adam, because we do not know what the year was; we can call it year one and work up, but we cannot work from the back to the front. Working backward, it is now fairly accepted, even among secular and liberal scholars, that the division of Solomon's monarchy into Rehoboam and Jeroboam happened in 931 B.C. That date is close enough to us, with enough surrounding evidence, that once it is established you can work back many years toward Adam. You run into a few difficulties along the way: the 430 years in Egypt, which Scripture insists on; the date the Babylonian captivity began, whether 609 or 587 B.C.; and Luke 3:36, which puts Cainan between Arphaxad and Shelah, whereas Genesis 11 does not, which leads some to argue that 'begot' need not mean a direct father-son relationship. With four or five such variables, and each one offering two or three ways to go, you end up with at least three dozen possible dates for Adam. What we need is more Bible study on these points and more archaeology to verify which way to go; archaeology has helped before, as when it finally found the Hittites it had once used to accuse the Bible of error. Get my commentary on Genesis 1 to 11 and you will see all these points laid out. Right now we have only educated guesses.
