Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.

Carbon-14 has a half-life of about 5730 years, and therefore it is used to date biological samples up to about 60,000 years in the past.

Samples significantly older than this have very little or even no measurable C left.Worse still, sometimes they want to know how evolutionists use Carbon-14 to date dinosaur fossils!Radiometric Dating Technologies are presented to the public by evolutionists as utterly reliable clocks for dating earth rocks or biological materials.The level of atmospheric C is not constant due to human activity, in part because of human combustion of fossil fuels and in part because of above-ground testing of the largely defensive weapon of the thermonuclear bomb.Therefore dates must be calibrated based on Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.They all start with similar flaws, but Carbon-14 has more than the rest.The Carbon-14 “dating” method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.Carbon-14 is a radioactive isotope formed in the upper atmosphere.It is constantly being produced by a system in which cosmic rays from the sun hit atoms, releasing neutrons. Carbon-14 becomes a part of the mostly homogenous mixture of air in the atmosphere.The use of carbon-14, also known as radiocarbon, to date organic materials has been an important method in both archaeology and geology.The technique was pioneered over fifty years ago by the physical chemist Willard Libby, who won the 1960 Nobel Prize for his work on C.
