Carbon dating accuracy
Something to note, carbon dating only really works on previously-living organisms, and only within a window of ~5,730 - ~50,000 years of age.

Recent field work yielded a surprisingly intact 3,000-year-old ... Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon). Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back ... Radiocarbon dating is based on the fact that the interaction of cosmic rays from outer space with nitrogen atoms in the atmosphere produces an unstable isotope of carbon, namely radiocarbon.
