Therefore, my main concern is with rocks of the Cambrian periods and later.Back to top Radioactive elements decay gradually into other elements.It just means that there is enough accuracy in the measurements to compute t to one or two percentage points of accuracy, where t is the time required to obtain the observed ratio of daughter to parent, assuming no initial daughter product was present at the beginning, and no daughter or parent entered or left the system.For isochrons, which we will discuss later, the conditions are different.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.In general, in n half-lives, only 1/(2^n) of the original parent material will be left.

If these dates are correct, this calls the Biblical account of a recent creation of life into question.The Cambrian period is conventionally assumed to have begun about 550 million years ago.
