How old is the earth according to radioactive dating - How Old Is The Earth? - Universe Today


Although early stratigraphers could determine the relative order of rock units and fossils, they could only estimate the lengths of time involved by observing the rates of present geologic processes and comparing the rocks produced by those processes with those preserved in the stratigraphic record. 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.

Simply put, it came from the Bible. Of course, the Bible doesn’t say explicitly anywhere, “The earth is 6,000 years old.” Good thing it doesn’t; otherwise it would be out of date the following year. But we wouldn’t expect an all-knowing God to make that kind of a mistake.

At some point in the early history of Earth, a planetoid the size of Mars crashed into our planet. The resulting collision sent debris into orbit that eventually became the Moon.
