When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.Scientists now realize that production of carbon-14 has not been constant over the years, but has changed as the radiation from the sun has fluctuated.These isotopes have longer half-lives and so are found in greater abundance in older fossils.Some of these other isotopes include: back to the last global catastrophe (i.e.Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.The mathematical premise undergirding the use of these elements in radiometric dating contains the similar confounding factors that we find in carbon-14 dating method.Most scientists today believe that life has existed on the earth for billions of years.
All dating methods that support this theory are embraced, while any evidence to the contrary, e.g. Prior to radiometric dating, evolution scientists used index fossils a.k.a. A paleontologist would take the discovered fossil to a geologist who would ask the paleontologist what other fossils (searching for an index fossil) were found near their discovery.Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.Other methods scientists use include counting rock layers and tree rings.the geological column and approximate ages of all the fossil-bearing strata were all worked out long before anyone ever heard or thought about radioactive dating …There are so many sources of possible error or misinterpretation in radiometric dating that most such dates are discarded and never used at all, notably whenever they disagree with the previously agreed-on [index fossil] dates.” (Dr Henry Morris, creationist scientist and hydraulicist, Ph D in hydrology, geology and mathematics, Fellow of the American Association for the Advancement of Science and the American Society of Civil Engineers, former Professor of Hydraulic Engineering at Virginia Polytechnic Institute, 1974) Michael Oard, Ph. is a meteorologist and creationist scientist who writes, And when it comes to dating any individual rock today, the resulting “date” is forced to conform to predetermined evolutionist “dates” based on these imaginary 19th century index-fossil “dates”.
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
