b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.

This method includes carbon dating and thermoluminescence.

The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.

The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.

is the study of the conditions under which plants, animals, and other organisms become altered after death and sometimes preserved as fossils.

Research into these matters has shown that fossilization is a rare phenomenon.

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.

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.Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.This method has the following restrictions: a) It cannot be used to date items many thousands of years old; b) it can only be used in non-organic materials; and c) the materials to be dated must have been heated to more than 350 degrees Celsius. All of the current dating methods are going through refinement.Archaeologists are seeking an accurate dating technique, but this method is yet to be found.
