the atmosphere has always been what it is today, which is one carbon-14 atom for every trillion carbon-12 atoms. Carbon-14 weighs 14 atomic mass units, rather than the more common 12 atomic mass units. It is called radio carbon because it is radioactive and half of it will decay in about 5730 years to form nitrogen. Half of the remainder will decay in another 5730 year, etc. Carbon-12 and 14 combine with oxygen to form radioactive carbon dioxide, which then spreads across the atmosphere. Plants absorb it in the same proportion as occurs in the atmosphere, (onecarbon-14 atom for each trillion carbon-12 atoms) and it then passes through the food chain to enter animal tissues, again in this same propo!rtion. When a plant or animal dies, it takes in no radio carbons, and the half-life(5730 years) clock starts ticking. The newer atomic accelerators can actually count the carbon-14 atoms in a fossil, rather than the less precise method of attempting to count the rare disintegration of carbon-14 atoms, which can be confused with other types of disintegration. Eleven of the earliest human remains have been dated at less than 5000 radiocarbon years, using the newer technique. (Taylor, 1985). Brown(1989) states that the Torah, the Koran and the Bible all describe a worldwide flood, and this flood would change the ratio of radiocarbon-14 to carbon-12 because there would be no forests or plants to recycle carbon dioxide with the atmosphere. With less carbon of both kinds to dilute the carbon-14 that forms in the upper atmosphere (currently at the rate of about 21 pounds per year), the ratio of carbon-14 would increase. Also, the oceans and the atmosphere exchange huge amounts !of carbon dioxide so as to maintain a balance. A radiocarbon year today could very well be only a year after the flood. There is considerable archaeological evidence indicating that Noah's Ark does exist, including ancient writings by Josephus, and Berosus o...
