    How old is the earth based on radiometric age dating

    Radioactive decay has become one of the most useful methods for determining the age of formation of rocks.

    However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid.

    These assumptions include: 1) the initial amount of the daughter isotope is known, 2) neither parent or daughter product has migrated into, or out of, the closed rock system, and 3) decay has occurred at a constant rate over time.

    But what if one or some combination of these assumptions is incorrect?

    This amount is often unknown and is one of the downfalls of conventional radiometric dating.

    However, isochron dating bypasses this assumption, as explained below. The final condition is the number of atoms of parent and daughter isotopes remaining in the rock and can easily be measured in a lab.

    Theoretically, Creationism remains workable within a wide range of age estimates.

    Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.For this purpose, isochron dating was developed, a process "that solves both of these problems (accurate date, assumptions) at once" (Stasson 1992). 2) The process must occur at a relatively uniform rate.It has been established through extensive experimentation that radioactive decay occurs at a constant rate. In this case, the initial condition is the amount of daughter isotope in the rock when it was formed.Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze (for example, Woodmorappe 1979; Morris HM 1985; Morris JD 1994).
