Many independent measurements have established that the Earth and the universe are billions of years old.

Their pristine interiors give an age that dates back to their formation at the beginning of the solar system.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 4.6 billion years.Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years.As time passes, a rock will have more and more Argon-40 and less and less Potassium-40.Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element.
