This is a the accuracy so clearly the isotope dating was wrong. In later years, the use of accelerator mass spectrometers and the introduction of high-precision dating dating have also generated calibration curves. Is there evidence for Creation science?

Coal is an obvious candidate because the youngest coal is supposed to be millions of years old, and most of it is supposed to be tens or hundreds of millions of years old. As long as an organism is alive it will continue to take in 14 C; however, when it dies, it will stop.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. In addition to permitting more accurate dating within archaeological sites than previous methods, it allows comparison of dates of events across great distances.

Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages. First, plants discriminate against carbon dioxide containing 14 C. The Pleistocene is a geological epoch that began about 2.
