Radiocarbon dating of ancient human remains has been used to expand the perceived timescale for human existence in Eurasia to over 40,000 years based on the uniformitarian assumption that atmospheric carbon 14 (C-14) concentration is unchanged relative to modern times. Stated as scientific facts with no discussion of the assumptions involved, these excessive ages challenge the record of world history recorded in the Bible and lend support to the notion that man has evolved from apes. Such reasoning is unacceptable by those who believe that the Bible is God's Word which cannot be overturned by any so-called "scientific" arguments. Rather, it is science in general, and radiocarbon dating in particular, which must be interpreted in a manner consistent with the true history of the world. Radiocarbon dating must be calibrated to fit a biblical timescale. The finding of C-14 in fossil fuels, which were derived from plants buried in the Flood, suggests a starting point for the correct calibration of radiocarbon dating by providing an ancient carbon of known age in which the C-14 content can be measured. The low content of C-14 in fossil fuels implies that the atmospheric C-14 level in the pre-Flood world was less than 1% of today's level, in dramatic contrast to the uniformitarian assumption of stable atmospheric C-14 levels. The process that has caused the increase in atmospheric C-14 since then is not known, but the increase was very rapid in the first centuries after the Flood. Based on C-14 measurements from two ancient carbons with biblical dates, the Flood at 2500 B.C. and the Joseph famine at 1875 B.C., and from tree rings from 1000 B.C., a radiocarbon dating curve is constructed to connect the Flood to 1000 B.C., the time of King David. Given the many assumptions and difficulties involved with C-14 measurements radiocarbon dating on a biblical timescale can only provide an approximate date for ancient carbons and cannot supplant absolute dating based on reliable historical records.
