This makes geology partially philosophical science since we never know the extent and real dimension of time. In this case our own place in time is just a flick among series of evolutionary events. However, as humans we are always ready to place ourselves as central or influential figures. Then we get a slap in the face from Mother Nature, but unfortunately we never learn. Geologists analyze geologic time in two different ways: in terms of relative geologic age , and in terms of absolute or numeric geologic age.

Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
