How old is the earth radiometric dating

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

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.

When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.
