There's a small amount of radioactive carbon-14 in all living organisms.

When they die no new carbon-14 is taken in by the dead organism.

When one considers the power of God, one sees that any such conclusions are to some extent tentative. Some fossils are found in Precambrian rocks, but most of them are found in Cambrian and later periods.

We can assume that the Precambrian rocks already existed when life began, and so the ages of the Precambrian rocks are not necessarily related to the question of how long life has existed on earth.

The Cambrian period is conventionally assumed to have begun about 550 million years ago.

Since Cambrian and later rocks are largely sedimentary and igneous (volcanic) rocks are found in Cambrian and later strata, if these rocks are really 550 million years old, then life must also be at least 550 million years old.

If these dates are correct, this calls the Biblical account of a recent creation of life into question.The carbon-14 it contained at the time of death decays over a long period of time.By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.Potassium is present in most geological materials, making potassium-argon dating highly useful if it really works.Potassium is about 1/40 of the earth's crust, and about 1/10,000 of the potassium is potassium 40.
