7.) Carbon-14 is a radioactive isotope of carbon. The half-life of carbon-14 is approximately 5,730 years. The short half-life of carbon-14 means it cannot be used to date fossils that are allegedly extremely old, e.g. dinosaurs the evolution alleges lived millions of years ago. Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).
