[DB 1506 (7); OAB 3] It is true that human civilization is recent, although its age is closer to 10,000-15,000 years than to 4,000. Everyone, except the young-Earth proponents themselves, agrees that human civilization is much younger than the Earth itself, thus the age of human civilization does not affect the age of the Earth unless you assume a young-Earth view in the first place. That, of course, would be circular reasoning.
