Time dating techniques

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.There are three main assumptions that must be made to accept radiometric dating methods.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.

Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.
