Rubidium strontium dating range
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.

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.
In exponential decay the amount of material decreases by half during each half-life.Most of the elements in nature are stable and do not change.However, some elements are not completely stable in their natural state.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.The goal is to promote greater understanding on this issue, particularly for the Christian community.
