For example, a study of the Amitsoq gneisses from western Greenland used five different radiometric dating methods to examine twelve samples and got agreement to within 30 million years on an age of 3,640my.Most people accept the current old-earth (OE) age estimate of around 4.6 billion years.This is based upon the spontaneous breakdown or decay of atomic nuclei.Radioactive parent (P) atoms decay to stable daughter (D) atoms e.g.A full discussion of the topic must therefore include the current scientific challenge to the OE concept.This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.For example, carbon dating is used to determine the age of organic materials.

Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last.The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.It may be used to date a wide range of natural and man-made materials.Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.
