The earth is roughly 4. We know this by a process known as radiometric dating. Radiometric dating works by measuring the amount of a radioactive isotope in a certain mineral. An isotope is a variation of the number of nuetrons, for each atom of an element. For example Hydrogen has 3 isotopes: H1, H2 and H3.

Radiometric Age Dating - Geology (U.S. National Park Service)

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.

Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers. Using the known rate of change in radio-active elements radiometric dating , some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4. Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years.
