Search for: Does carbon dating prove the earth is millions of years old? 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. 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 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. In theory it would never totally disappear, but after about 5 half-lives the difference is not measurable with any degree of accuracy.

This is why most people say carbon dating is only good for objects less than 40, years old. Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years. Willard Libby invented the carbon dating technique in the early s. The amount of carbon 14 in the atmosphere today is about. Since sunlight causes the formation of C in the atmosphere, and normal radioactive decay takes it out, there must be a point where the formation rate and the decay rate equalizes.

This is called the point of equilibrium. To illustrate: If you were trying to fill a barrel with water but there were holes drilled up the side of the barrel, as you filled the barrel it would begin leaking out the holes.

At some point you would be putting it in and it would be leaking out at the same rate. You will not be able to fill the barrel past this point of equilibrium. In the same way the C is being formed and decaying simultaneously. A freshly created earth would require about 30, years for the amount of C in the atmosphere to reach this point of equilibrium because it would leak out as it is being filled.

Tests indicate that the earth has still not reached equilibrium. There is more C in the atmosphere now than there was 40 years ago. This would prove the earth is not yet 30, years old! This also means that plants and animals that lived in the past had less C in them than do plants and animals today. Just this one fact totally upsets data obtained by C dating. Animals eat the plants and make it part of their tissues. A very small percentage of the carbon plants take in is radioactive C When a plant or animal dies, it stops taking in air and food so it should not be able to get any new C The C in the plant or animal will begin to decay back to normal nitrogen.

The older an object is, the less carbon 14 it contains. One gram of carbon from living plant material causes a Geiger counter to click 16 times per minute as the C decays. A sample that causes 8 clicks per minute would be 5, years old the sample has gone through one half-life and so on. The Assumptions of Carbon Dating Although this technique looks good at first, carbon dating rests on at least two simple assumptions.

These are, obviously, the assumption that the amount of carbon 14 in the atmosphere has always been constant and that its rate of decay has always been constant. Neither of these assumptions is provable or reasonable. An illustration may help: Imagine you found a candle burning in a room, and you wanted to determine how long it was burning before you found it.

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. 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. 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. Shells from living snails were carbon dated as being 27, years old.

Radiometric dating would not have been feasible if the geologic column had not been erected first. Printing Office, p. About the Author: Eric Hovind Eric Hovind grew up immersed in the world of apologetics and following college graduation in , he began full-time ministry.

If something carbon dates at 7, years we believe 5, is probably closer to reality just before the flood. Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years. One of the impressive points Whitewall makes is the conspicuous absence of dates between 4, and 5, years ago illustrating a great catastrophe killing off plant and animal life world wide the flood of Noah!

I hope this helps your understanding of carbon dating. If you have any more questions about it don't hesitate to write. I just listened to a series of lectures on archaeology put out by John Hopkins Univ. The lecturer talked at length about how inaccurate C14 Dating is as 'corrected' by dendrochronology.

The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error. Despite this she continually uses the c14 dates to create 'absolute' chronologies. She says this is ok so long as you take into account the correction factors from dendrochronology. They conveniently forget to mention that the tree ring chronology was arranged by C14 dating.

The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which using the bristlecone pine. So they tested some of the ring sequences by C14 to put the sequences in the 'right' order. Once they did that they developed the overall sequence. And this big sequence is then used to 'correct' C14 dates. Talk of circular reasoning!!!! Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question.

Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay. This skews the 'real' answer to a much younger age.
