During the 19th century, and even well into the twentieth, geological chronology was very crude. Dates were estimated according to the supposed rate of deposition of rocks, and figures of several hundred million years were bandied out; usually arrived at through inspired guesswork rather than anything else. With the discovery of radiometric dating, it became possible for the first time to attempt precise figures. Radiometric dating works on the principle that certain atoms and isotopes are unstable. These unstable atoms tend to "decay" into stable ones; they do this by emitting a particle or particles. This emission is what is known as radioactivity.

It is not about the theory behind radiometric dating methods, it is about their application , and it therefore assumes the reader has some familiarity with the technique already refer to "Other Sources" for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

Different world-views have different time-scales as regards the history of the Earth and the universe. Buddhist , Jain and Hindu cosmologies describe the universe as a never-ending series of cycles each lasting millions or billions of years. The Greeks had the "great year" of 24, years, based on the precession of the equinoxes. The time-scale of the fundamentalist or Creationist Judeo-Christian is based on a word-for-word reading of the first book of the Bible, and assumes a total age of the earth and the cosmos of a mere 5 or 6, some Creationists allow 10, years.
