Methods of dating the age of the earth

Archbishop Ussher took the genealogies of Genesis, assuming they were complete, and calculated all the years to arrive at a date for the creation of the earth on Sunday, October 23, 4004 B. Of course, even assuming the method was valid, such an exact date is not possible from the genealogies of the Bible (Ussher assumed all the years the patriarchs lived were exactly 365.25 days long and that they all died the day before their next birthday).There are a number of other assumptions implicit in the calculation.In reality, the Bible makes no claim as to the age of the earth, although it does establish a minimum age.This page examines some of the history of the controversy—what the Bible actually says and does not say—and the scientific evidence surrounding the age of the earth.magazine has been continuously published since 1978, we are publishing some of the articles from the archives for historical interest, such as this.

The second assumption is that the Genesis creation "days" were exactly 24-hours in length. Although Archbishop Ussher assumed the Genesis genealogies were complete, it is clear from the rest of the Bible that those genealogies were telescoped (some names were left out for the sake of brevity), which is common in biblical genealogies but rare in modern genealogies.

Second, it is impossible to tell, from the isotope information alone, when the dates are right and when they are wrong.

When I presented this and similar criticisms of isotope dating to a gathering of the Lucas Heights Scientific Society (Sydney, Australia) in 1989, the only response that came from the chief of the division responsible for isotope dating at the Australian Nuclear Science and Technology Organization was the question, ‘Do you have a better dating method?

A serious problem here is that all 140 crystals from the same rock unit gave statistically valid information about that rock unit.

No statistician could ever condone a method which selected one value and discarded all the other 139. They found what might have been the world’s oldest rock crystals, but unfortunately they were too old!
