Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14 C. This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings. The half-life of 14 C is approximately years, which is too short for this method to be used to date material millions of years old.

Archaeologists are seeking an accurate dating technique, but this method is yet to be found. Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.
Even though more than one method of verification is used in most cases, the lack of an accurate method to date non-organic materials lends a certain degree of uncertainty to the accepted history of our planet.
It is also important not to forget that throughout the history of humankind any discovery that shakes the status quo is always under attack until it becomes established, and we are in an era where many of the things that we once considered certain will become errors of our past.

Matching the pattern in trees whose age is known to the pattern in wood found at an archaeological site can establish the age at which the wood was cut and thus the approximate date of the site.
