Radiocarbon dating is a technique for determining the age of very old objects consisting of organic carbon-based materials, such as wood, paper, cloth, and bone. The technique is based on the fact that both stable and radioactive isotopes of carbon exist. These isotopes behave almost identically in biological, chemical, and physical processes. Radioactive carbon is formed in the atmosphere when neutrons produced in cosmic ray showers react with nitrogen atoms.

A cave drawing in Borneo is at least 40, years old, raising intriguing questions about creativity in ancient societies. Cave paintings in Spain were made by Neanderthals, not modern humans, archaeologists reported.
Prior to the 20th century, estimating the age of ancient fossils or artifacts was considered a job of a paleontologist or archaeologist. The age of silt layers or rocks was found which served as a reference to the estimate the age of an artifact or a fossil. Although, a relic discovered in frozen ice, caves or places whose age remains unknown made it hard to date it in an accurate manner. So when the process of carbon dating was proposed, the nuclear physicists could determine the approximate age of ages old objects, fossils and extinct materials.
