14c and carbon dating
Absolute dating represents the absolute age of the sample before the present.
Natural disasters like floods can sweep away top layers of sites to other locations.
In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.
Although relative dating can work well in certain areas, several problems arise.
The Greeks consider the first Olympic Games as the beginning or 776 BC.
The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.
