At first, there weren’t many strategies of relationship had been obtainable, but now with development in the technology, we primarily have two kinds of techniques to ascertain ages of historic belongings. Relative Dating and Absolute Dating are two types of such methods which are underneath practice to find out the age of the fossils, objects or civilizations.
