But Earth’s layers of rock did not give up the secret of Earth’s age easily. However, from working with layer upon layer of rock laid down on Earth over long time spans, early 20th century scientists came to believe Earth not of atoms of one chemical element into another.

They led to the discovery that certain very heavy elements could decay into lighter elements – such as uranium decaying into lead.

With the development of modern radiometric dating methods in the late 1940s and 1950s, it was possible for the first time not only to measure the lengths of the eras, periods, and epochs but also to check the relative order of these geologic time units.

Radiometric dating verified that the relative time scale determined by stratigraphers and paleontologists (Figure 1) is absolutely correct, a result that could only have been obtained if both the relative time scale and radiometric dating methods were correct.

Many great thinkers throughout history have tried to figure out Earth’s age.

For example, back in 1862, Lord Kelvin calculated how long Earth might have taken to cool from its original molten state.

Another role of isotopic geochemistry that is of great importance in geology is radiometric age dating. Beginning with studies in the 1950s, a much better chronology and record of Pleistocene climatic events have evolved through analyses of deep-sea sediments, particularly from the oxygen isotope record of the shells of microorganisms that lived in the oceans.

There are at least 67 different uniformitarian (the present is the key to the past) methods of dating the earth other than long-age radiometric dating: each of which yield ages of less than 500 million years.

Yet all these other science-based methods that point to a much younger age than 4.5 billion years for earth's age are ignored or rejected by evolution-believing people with degrees from college who apparently think that nobody (of importance) made them. Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth's age many years ago.

...igneous activity (both extrusive and intrusive) occurred in the Caledonian mountain belt, which stretched from New England, Nova Scotia, Newfoundland, Scotland, and Scandinavia to eastern Greenland.

Radiometric dating of granitic intrusions associated with the Caledonian orogeny yields ages between about 430 million and 380 million years.

efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.
