Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon

Does carbon dating prove the earth is millions of years old?
Carbon isotope dating is only effective up to about 70, years. Dinosaur bones are at least 65 million years old. Elements with much longer half-lives are used to radiometrically date rock associated with dinosaur remains.
To know if carbon dating is accurate, we would have to know how much carbon was in the atmosphere in the beginning, and also how long it has been increasing, or decreasing. Since no one was there, no one knows for sure. It's like trying to figure out how long a candle has been burning, without knowing the rate at which it burns, or its original size.
