Radiometric dating age of earth
In plain language the radiometric estimates for the age of the earth are lacking real foundations Concordant data It might be argued that although radiometric dating has a few problems the large body of concordant data using different isotopes shows that the dates are of the right order In fact there is no large body of concordant data
