Carbon 14 (C-14) dating was considered to be a tremendous breakthrough in science when Willard Libby devised it in 1946. Read, Journal of Near Eastern Studies, Vol, 29, No. Thus, the meaning of dates by C-14 prior to 1600 B. "If the earth and life on earth are really as ancient as the theory of evolution requires, a great proportion of radiocarbon ages should be infinite.But subsequent investigations have revealed it to be wholly inadequate for accurate dating of ancient materials. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts. This is because, with a half-life of only 5,730 years, initial radiocarbon in a fossil decreases in about ten half-lives to a level too low to be measured."—Robert E.Thus they probably formed at a depth of 100–200 km.Geologists believe that the ones we find must have been transported supersonically to the surface, in extremely violent eruptions through volcanic pipes.Tests by other scientists using paleomagnetism and fission tracks confirmed the lower date.So by 1980 there was a new, remarkably concordant date for the KBS tuff, and this became the one that was widely accepted. "[d] Deep ocean deposits supposed to contain remains of most primitive life forms are dated within 40,000 years. "[b] Only three of the 15,000 reported ages are listed as `infinite.' "[c] Some samples of coal, oil, and natural gas, all supposedly many millions of years old have radiocarbon ages of less than 50,000 years.
Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better. von Fange, "Time Upside Down," in Creation Research Society Quarterly, June 1974, p. "Although it was hailed as the answer to the prehistorian's prayer when it was first announced, there has been increasing disillusion with the [radiocarbon] method because of the chronological uncertainties—in some cases absurdities—that would follow a strict adherence to published C-14 dates . What bids to become a classic example of `C-14 irresponsibility' is the 6,000 year spread of 11 determinations for Jarmo, a prehistoric village in northeastern Iraq which, on the basis of all archeological evidence, was not occupied for more than 500 consecutive years."—*C. Reed, "Animal Domestication in the Prehistoric Near East," in Science, 130 (1959), p. "A survey of the 15,000 radiocarbon dates published through the year 1969 in the publication, Radiocarbon, revealed the following significant facts: "[a] Of the dates of 9,671 specimens of trees, animals, and man, only 1,146 or about 12 percent have radiocarbon ages greater than 12,530 years. By contrast, this revised approach has the effect of `compressing' radiocarbon time,' and speeding up the rate of man's cultural development."—Erich A.Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.
