Absolute dating tells you

After yet another 5,730 years only one-eighth will be left.

One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.Carbon-14 moves up the food chain as animals eat plants and as predators eat other animals. It takes 5,730 years for half the carbon-14 to change to nitrogen; this is the half-life of carbon-14.After another 5,730 years only one-quarter of the original carbon-14 will remain.Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.

Michele Hutchinson said, “As long as the person is a good, honest, person, then race shouldn’t really be a factor in [her child’s] decision.” PTA Executive Board Representative Jordan Leeds agreed with this sentiment, stating that he hopes “the fact that my children were raised in a very diverse community [means] that they’re open to every race or religion” and that he doesn’t “want them to avoid [dating someone of a different race or religion] because of me.” One anonymous parent, however, did say that she “would probably prefer if she dated someone of the same race,” but that she “wouldn’t forbid my child to date someone of a different race solely because of that person’s race.” The United States once had laws forbidding interracial and interethnic marriage., which were then repealed in 1967.
