Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon This radioactive carbon 14 slowly decays back into normal, stable nitrogen. Extensive laboratory testing has shown that about half of the C molecules will decay in 5, years. This is called the half-life.
Carbon has a half-life of about years, so researchers use the process to date biological samples up to about 60, years in the past. Beyond that timespan, the amount of the original C 14 remaining is so small that it cannot be reliably distinguished from C 12 formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.
For older samples, other dating methods must be used. The level of atmospheric C 14 is not constant.
Does carbon dating prove the earth is millions of years old?
Atmospheric C 14 varies over decades due to the sunspot cycle, and over millennia due to changes in the earth's magnetic field. On a shorter timescale, humans also affect the amount of atmospheric C 14 through combustion of fossil fuels and above-ground testing of the largely diplomatic weapon of the thermonuclear bomb.
Therefore dates must be calibrated based on C 14 levels in samples of known ages. Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is odd years old.
A favorite tactic of Young-Earthers involves citing studies which show trace amounts of C 14 in coal or diamond samples, which - being millions of years old - should have no original atmospheric C 14 left.
Recent studies, however, show that C 14 can form underground. The decay of uranium and thorium, among other isotopes, produces radiation which can create C 14 from C This fact is extremely inconvenient to YECs, and creationist literature, accordingly, usually does not mention it.
Carbon-dating skeptics deniers also claim that the inconsistency of C 14 levels in the atmosphere over the past 60, years creates causes a validity issue.
However, calibration of carbon levels using tree rings and other sources keep such effects to an extremely small level.
Ironically, given how supposedly useless carbon dating is claimed to be, Creation Ministries International rests part of their " Evidences" on carbon dating being a useful method for within several thousand years.
This of course contradicts claims that the Great Flood messed up how carbon was deposited, destroying their own argument. Less astute creationists often conflate carbon dating with other forms of radiometric dating, attempting to "disprove" the true age of dinosaur fossils by "refuting" carbon dating.
They have been slowly built up by matching ring patterns between trees of different ages, both living and dead, from a given locality. As one might expect, the further back the tree-ring chronology extends, the more difficult it becomes to locate ancient tree specimens with which to extend the chronology.
To alleviate this problem it seems, from the published literature, to be a common practice to first radiocarbon date a large number of potential tree specimens and then select those with appropriate radiocarbon age for incorporation into the tree-ring chronology. Such a procedure introduces a bias into the construction of the tree-ring chronology for the earliest millennia which could possibly obscure any unexpected radiocarbon behavior.
It is not clear to what extent this circular process has influenced the final tree-ring calibrations of radiocarbon.

Download Carbon Dating Undercuts Evolution's Long Ages Even if they cannot provide a naturalistic mechanism, they appeal to the "fact of evolution," by which they mean an interpretation of earth history with a succession of different types of plants and animals in a .

How Carbon Dating Works Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon
Efforts by creationist scientists to obtain the raw data from which the oldest tree-ring chronology has been constructed to investigate this possible source of bias have so far not met with success. Until the raw data does become available for general scrutiny, creationists are clearly justified in maintaining a high degree of skepticism.
In any event, the calibration tables which have been produced from tree rings do not support the conventional steady-state model of radiocarbon which Libby introduced.
Radiometric Dating Debunked in 3 Minutes
Rather, they lend support to the idea that significant perturbations to radiocarbon have occurred in the past. Creationists are interested in the truth. This involves exposing areas of weakness and error in the conventional interpretation of radiocarbon results as well as suggesting better understandings of radiocarbon congruent with a Biblical, catastrophist, Flood model of earth history.
Nov 19, ICR creationists claim that this discredits C dating. How do you reply? Answer: It does discredit the C dating of freshwater mussels, but that's about all. Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well. Creationists have nothing to fear from carbon dating, as it does not disprove the young age of the earth. The carbon dating method is based largely on unverifiable assumptions that are . Jan 01, Because they start from the answer, and work back to the evidence, rejecting anything that disagrees with their answer. Many creationists, particularly Young Earth Creationists,are happy to accept any science that doesn't conflict with their belie.
At ICR research into alternative interpretations of radiocarbon which are not in conflict with the Biblical record of the past continue to be actively pursued and a special radiocarbon laboratory is being developed for research into the method.
Radiocarbon holds unique potential for the student of earth history who adheres to a recent creation. It is doubtful that other radiometric dating techniques such as potassium-argon or rubidium-strontium will ever be of much value or interest to the young-earth creationist who desires to develop further our understanding of the past because they are only applicble on a time scale of millions or billions of years.
Radiocarbon, however, is applicable on a time scale of thousands of years. A proper understanding of radiocarbon will undoubtedly figure very significantly into the unraveling of such questions as when and possibly why the mammoths became extinct, the duration of the glacial period following the Flood, and the general chronology of events from the Flood to the present. Creationists are not so much interested in debunking radiocarbon as we are in developing a proper understanding of it to answer many of our own questions regarding the past.
Creationists will also point to examples where freshly killed animals are carbon-dated as being thousands of years old-thus, we're told, these dating methods cannot be trusted. For example, we read on mariechloepujol.com that. The field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by Libby in the late 's. It is, therefore, not surprising that many misconceptions about what radiocarbon can or cannot do and what it has or has not shown are prevalent among creationists and evolutionists - lay people as well as scientists not. Apr 17, I think what the question s really getting at is 'Why do evolutionists explain away the presence of C14 in dinosaur fossils?' The answer is that the conclusion must be consistent with a priori beliefs. IOW if you BELIEVE something is 65 million y.
At the present time it appears that the conventional radiocarbon dating technique is on relatively firm ground for dates which fall within the past 3, years. For periods of time prior to this, there are legitimate reasons to question the validity of the conventional results and seek for alternative interpretations.

Myths Regarding Radiocarbon Dating. Skip to main content. MYTH 6. Creationists are only interested in debunking radiocarbon. The Latest. You could measure the present height of the candle say, 7 inches and the rate of burn say, an inch per hour.
In order to find the length of time since the candle was lit, we would be forced to make some assumptions. We would, obviously, have to assume that the candle has always burned at the same rate, and assume an initial height of the candle.
Carbon dating creationists
The answer changes based on the assumptions. Similarly, scientists do not know that the carbon decay rate has been constant.
They do not know that the amount of carbon 14 in the atmosphere is constant. Present testing shows the amount of C in the atmosphere has been increasing since it was first measured in the s. This may be tied in to the declining strength of the magnetic field. In addition to the above assumptions, dating methods are all subject to the geologic column date to verify their accuracy.
If a date obtained by radiometric dating does not match the assumed age from the geologic column, the radiometric date will be rejected.
The so-called geologic column was developed in the early s over a century before there were any radio- metric dating methods. There are about 7 or 8 radioactive elements that are used today to try to date objects.
The Assumptions of Carbon Dating
Each one has a different half-life and a different range of ages it is supposed to be used for. No dating method cited by evolutionists is unbiased. ThousandsNot Billions eBook by Dr.
Don DeYoung. Does carbon dating prove the earth is millions of years old? How Carbon Dating Works Radiation from the sun strikes the atmosphere of the earth all day long.
The Assumptions of Carbon Dating Although this technique looks good at first, carbon dating rests on at least two simple assumptions. Radiometric dating would not have been feasible if the geologic column had not been erected first.
