However, there are many methods that can be used to determine the age of the earth or other objects.The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.The dates must be inferred based on assumptions about the ratios.The method of calculating radiometric dates is like using an hourglass.You can use the hourglass to tell time if you know several things: the amount of sand in the top of the hourglass when it started flowing, the rate that the sand flows through the hole in the middle, and that the quantity of sand in each chamber has not been tampered with.

Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.For example, if you began with 1 gram of carbon-14, after 5,730 years you would be left with 0.50 g and only 0.25 g after 11,460 years.Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
