Radiometric dating techniques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old.Many Christians accept this and interpret the Genesis account in less scientifically literal ways.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

Similarly, when all the atoms of the radioactive element are gone, the rock will no longer keep time (unless it receives a new batch of radioactive atoms).

The rate of loss of sand from from the top of an hourglass compared to exponential type of decay of radioactive elements.

Even though the Earth's age is never mentioned in the Bible, it is an issue because those who take a strictly literal view of the early chapters of Genesis can calculate an approximate date for the creation by adding up the life-spans of the people mentioned in the genealogies.

Assuming a strictly literal interpretation of the week of creation, even if some of the generations were left out of the genealogies, the Earth would be less than ten thousand years old.Most of the elements in nature are stable and do not change.However, some elements are not completely stable in their natural state.Some of the atoms eventually change from one element to another by a process called radioactive decay.If there are a lot of atoms of the original element, called the parent element, the atoms decay to another element, called the daughter element, at a predictable rate.This paper is available on the web via the American Scientific Affiliation and related sites to promote greater understanding and wisdom on this issue, particularly within the Christian community.
