Adding up the generations from Adam, assuming there are none skipped, gives the 6000 year figure.
I’m drawing from the work of John Lennox, “Seven Days That Divide the World.”
Most commonly, the 6000 year controversy is used by anti Christian zealots to attack the faithful. It’s rarely if ever discussed from a sincere perspective.
I recommend John Lennox to anyone who has an opinion on this topic and is at risk of abandoning meaningful thought in the name of mainstream trends and conformity in general.

Aye, there's the rub.
