Radiometric dating is not an absolute science since it must be based on assumptions; radiometric dating can only estimate an “apparent age.” As the executive director of the National Center for Science Education, Eugenie Scott, explains in : “If certain assumptions are made about it [radiometric dating], then, it can yield a date which could be called the apparent age.Whether or not the apparent age is the true age depends completely on the validity of the assumptions.” The quantitative study of geological time is known as geochronometry−a branch of geochronology.These non-radiometric indicators include – Estimating the Earth to be millions and billions of years was popular in during the nineteenth century with the early uses of radiometric dating confirming Hershel’s “many thousand million years.”Since then, investigators have increasingly recognized the limitations of radiometric dating techniques, especially in the context of non-radiometric dating techniques, to establish an age for the Earth.
However, with radiometric dating, the different techniques often give different results.” The age measured from radiometric dating of rocks from the Grand Canyon by Austin was 10,000 years using the Potassium-Argon (K-Ar) method but 2,600,000 years with the Lead-Lead (Pb-Pb) method. Within the realm of science, arbitrarily selecting data is an act of flagrant fraud.
As Scott points out further, radiometric dating can only yield unproven dates since To test the validity of radiometric dating on newly formed rocks, in 1993 Austin submitted newly formed molten rocks recovered from the 1980 eruption of Mount Saint Helens volcano to the Geochron Laboratories of Cambridge, MA for dating using the K-Ar method.
While expecting as age of 13 years, the laboratory reported a staggering dating range from 340,000 to 2.8 million years.
A long-age of the Earth is an absolute pre-requisite for the theory of biological evolution.
Based on evidence from radiometric dating, the age of the Earth has been estimated to be approximately 4.5 billion years.
