Doesn’t Carbon-14 Dating Disprove the Bible?

However, things are not quite so simple. Radiocarbon dating data is certainly not compatible with any sort of old-earth model. Carbon 14 C , also referred to as radiocarbon, is claimed to be a reliable dating method for determining the age of fossils up to 50, to 60, years.

Radioactive decay releases helium into the atmosphere, but not much is escaping. The interpretation of past events is in question. The amount of carbon 14 in the atmosphere today is about. It is very much driven by the existing long-age world view that pervades academia today. Efforts to salvage carbon dating are many and varied, with calibration curves attempting to bring the C "dates" in line with historical dates, but these produce predictably unreliable results. Ham, Andrew Snelling and Carl Wieland. Confirmation of Rapid Metamorphism of Rocks.

Accordingly, carbon dating carefully applied to items from historical times can be useful. However, even with such historical calibration, archaeologists do not regard 14 C dates as absolute because of frequent anomalies.

They rely more on dating methods that link into historical records. Outside the range of recorded history, calibration of the 14 C "clock is not possible. The amount of cosmic rays penetrating the Earth's atmosphere affects the amount of 14 C produced and therefore dating the system.

The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy. The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere.

A stronger magnetic field deflects more cosmic rays away from the Earth. Overall, the energy of the Earth's magnetic field has been decreasing, [5] so more 14 C is being produced now than in the past. This will make old things look older than they really are. Also, the Genesis flood would have greatly upset the carbon balance. The flood buried a huge amount of carbon, which became coal, oil, etc. Total 14 C is also proportionately lowered at this time, but whereas no terrestrial process generates any more 12 C, 14 C is continually being produced, and at a rate which does not depend on carbon levels it comes from nitrogen.

Unless this effect which is additional to the magnetic field issue just discussed were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages.

Creationist researchers have suggested that dates of 35, - 45, years should be re-calibrated to the biblical date of the flood. Also, volcanoes emit much CO 2 depleted in 14 C.

Since the flood was accompanied by much volcanism see Noah's Flood… , How did animals get from the Ark to isolated places? In summary, the carbon method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully.

It does not give dates of millions of years and when corrected properly fits well with the biblical flood. There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks. These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.

For example, potassium decays to argon; uranium decays to lead via other elements like radium; uranium decays to lead; rubidium decays to strontium; etc. These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification. The isotope concentrations can be measured very accurately, but isotope concentrations are not dates.

To derive ages from such measurements, unprovable assumptions have to be made such as:. The starting conditions are known for example, that there was no daughter isotope present at the start, or that we know how much was there.

There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. However, there are still patterns to be explained.

Geologist John Woodmorappe, in his devastating critique of radioactive dating, [8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay.

The common application of such posterior reasoning shows that radiometric dating has serious problems. For example, researchers applied posterior reasoning to the dating of Australopithecus ramidus fossils. So they looked at some basalt further removed from the fossils and selected 17 of 26 samples to get an acceptable maximum age of 4.

The other nine samples again gave much older dates but the authors decided they must be contaminated and discarded them. That is how radiometric dating works. It is very much driven by the existing long-age world view that pervades academia today.

Various other attempts were made to date the volcanic rocks in the area. Over the years an age of 2. After this was widely accepted, further studies of the rocks brought the radiometric age down to about 1. Such is the dating game. Are we suggesting that evolutionists are conspiring to massage the data to get what they want? It is simply that all observations must fit the prevailing paradigm. We must remember that the past is not open to the normal processes of experimental science, that is, repeatable experiments in the present.

A scientist cannot do experiments on events that happened in the past. Scientists do not measure the age of rocks, they measure isotope concentrations, and these can be measured extremely accurately. Those involved with unrecorded history gather information in the present and construct stories about the past. The level of proof demanded for such stories seems to be much less than for studies in the empirical sciences, such as physics, chemistry, molecular biology, physiology, etc.

Williams, an expert in the environmental fate of radioactive elements, identified 17 flaws in the isotope dating reported in just three widely respected seminal papers that supposedly established the age of the Earth at 4. The forms issued by radioisotope laboratories for submission with samples to be dated commonly ask how old the sample is expected to be.

If the techniques were absolutely objective and reliable, such information would not be necessary. If the long-age dating techniques were really objective means of finding the ages of rocks, they should work in situations where we know the age.

Furthermore, different techniques should consistently agree with one another. The secular scientific literature lists many examples of excess argon causing dates of millions of years in rocks of known historical age. This is consistent with a young world—the argon has had too little time to escape. So data are again selected according to what the researcher already believes about the age of the rock. Steve Austin sampled basalt from the base of the Grand Canyon strata and from the lava that spilled over the edge of the canyon.

By evolutionary reckoning, the latter should be a billion years younger than the basalt from the bottom. Standard laboratories analyzed the isotopes. The rubidium-strontium isochron technique suggested that the recent lava flow was Ma older than the basalts beneath the Grand Canyon—an impossibility. If the dating methods are an objective and reliable means of determining ages, they should agree. If a chemist were measuring the sugar content of blood, all valid methods for the determination would give the same answer within the limits of experimental error.

However, with radiometric dating, the different techniques often give quite different results. In the study of the Grand Canyon rocks by Austin, different techniques gave different results. Techniques that give results that can be dismissed just because they don't agree with what we already believe cannot be considered objective.

In Australia, some wood found the Tertiary basalt was clearly buried in the lava flow that formed the basalt, as can be seen from the charring. Isotope ratios or uraninite crystals from the Koongarra uranium body in the Northern Territory of Australia gave lead-lead isochron ages of Ma, plus or minus Ma. The latter figures are significant because thorium-derived dates should be the more reliable, since thorium is less mobile than the uranium minerals that are the parents of the lead isotopes in lead-lead system.

Carbon Dating in many cases seriously embarrasses evolutionists by giving ages that are much younger than those expected from their model of early history.

A specimen older than 50, years should have too little 14 C to measure. Laboratories that measure 14 C would like a source of organic material with zero 14 C to use as a blank to check that their lab procedures do not add 14 C.

Coal is an obvious candidate because the youngest coal is supposed to be millions of years old, and most of it is supposed to be tens or hundreds of millions of years old. Such old coal should be devoid of 14 C.

No source of coal has been found that completely lacks 14 C. It is an unsolved mystery to evolutionists as to why coal has 14 C in it, [25] , or wood supposedly millions of years old still has 14 C present, but it makes perfect sense in a creationist world view.

Of the methods that have been used to estimate the age of the Earth, 90 percent point to an age far less than the billions of years asserted by evolutionists. A few of them follow. Evidence for a rapid formation of geological strata, as in the biblical flood.

Some of the evidences are: For more, see books by geologists Morris [26] and Austin. Red blood cells and hemoglobin have been found in some unfossilized! But these could not last more than a few thousand years—certainly not the 65 Ma since the last dinosaurs lived, according to evolutionists.

The Earth's magnetic field has been decaying so fast that it looks like it is less than 10, years old. Rapid reversals during the flood year and fluctuations shortly after would have caused the field energy to drop even faster. Radioactive decay releases helium into the atmosphere, but not much is escaping. This helium originally escaped from rocks. This happens quite fast, yet so much helium is still in some rocks that it has not had time to escape—certainly not billions of years.

A supernova is an explosion of a massive star—the explosion is so bright that it briefly outshines the rest of the galaxy. The supernova remnants SNRs should keep expanding for hundreds of thousands of years, according to physical equations. Yet there are no very old, widely expanded Stage 3 SNRs, and few moderately old Stage 1 ones in our galaxy, the Milky Way, or in its satellite galaxies, the Magellanic Clouds.

The moon is slowly receding for the Earth at about 4 centimeters 1. But even if the moon had started receding from being in contact with the Earth, it would have taken only 1. This gives a maximum age of the moon, not the actual age. This is far too young for evolutionists who claim the moon is 4. Salt is entering the sea much faster than it is escaping.

The sea is not nearly salty enough for this to have been happening for billions of years. Even granting generous assumptions to evolutionists, the sea could not be more than 62 Ma years old—far younger than the billions of years believed by the evolutionists. Again, this indicates a maximum age, not the actual age. Russell Humphreys gives other processes inconsistent with billions of years in the pamphlet Evidence for a Young World.

Creationists cannot prove the age of the Earth using a particular scientific method, any more than evolutionists can. They realize that all science is tentative because we do not have all the data, especially when dealing with the past. The atheistic evolutionist W. In reality, all dating methods, including those that point to a young Earth, rely on unprovable assumptions. Creationists ultimately date the Earth historically using the chronology of the Bible.

This is because they believe that this is an accurate eyewitness account of world history, which bears the evidence within it that it is the Word of God , and therefore totally reliable and error-free. What the do the radiometric dates of millions of years mean, if they are not true ages? To answer this question, it is necessary to scrutinize further the experimental results from the various dating techniques, the interpretations made on the basis of the results and the assumptions underlying those interpretations.

The isochron dating technique was thought to be infallible because it supposedly covered the assumptions about starting conditions and closed systems. This problem cannot be overlooked, especially in evaluating the numerical time scale. Similar questions can also arise in applying Sm-Nd [samarium-neodymium] and U-Pb [uranium-lead] isochron methods.

Clearly, there are factors other than age responsible for the straight lines obtained from graphing isotope ratios. Another currently popular dating method is the uranium-lead concordia technique.

This effectively combines the two uranium-lead decay series into one diagram. Numerous models, or stories, have been developed to explain such data. Again, the stories are evaluated according to their own success in agreeing with the existing long ages belief system. Andrew Snelling has suggested that fractionation sorting of elements in the molten state in the Earth's mantle could be a significant factor in explaining the ratios of isotope concentrations which are interpreted as ages.

Actual scientists understand that you have to be careful with carbon dating. They know it's not going to give accurate results for samples over 50, years old, or samples that don't contain any carbon at all. Furthermore, you have to watch out for samples that could possibly be contaminated with older or younger carbon, and you've got to watch out for the reservoir effect, which is where say, the shell of a marine organism will date much older than it actually is, becuase the carbon circulating at the bottom of a reservoir and the carbon circulating elsewhere isn't the same if you google reservoir effect you can easily find more information on exactly why this is Basically, the creationists are using logic that goes like this, just for carbon dating instead of hair dryers: Hair dryers do not function when they aren't plugged in, or have some other source of electrical power.

Therefore, all hair dryers are useless under all circumstances. As for whether or not other methods are used, the answer is also of course yes! Other methods have always been used, and they all of course have their own limitations to them. The limitations are known, and you don't use them when you can't get an accurate result unless you're a creationist.

Many of these other techniques overlap the date range applicable with carbon dating, and when multiple techniques can and are used on the same sample, there is extremely good agreement between the dates So, some other dating methods are by no means an extensive list: Dendrochronology Thermoluminescence Uranium-uranium Uranium-lead-helium Rhenium-osmium Neon-neon Lutetium-hafnium lead-lead lanthanum-barium iodine-xenon argon-argon chlorine 36 fission track dating uranium-thorium rubidium-strontium potassium-argon samarium-neodymium uranium-lead.

Yes, it is still used. By comparing successive tree rings, a concise year-by-year record can be obtained. Samples can often be dated within very tight ranges. The limit of accuracy is a few percent depending on the quality of the sample.

While science haters not all theists are against science try to peg it as inaccurate, it has enormous power if it is used within its limits. It can only estimate when carbon was taken up by plants. If termites burrow into the center of a year old tree, the termites will date years back.

If a builing was made from a year old tree 50 years after it died, the wood will date years older than the building, depending on the sample.

There are a variety of other methods. Thermoluminescence is excellent for pottery, for example. Other have gone 2 mre technological advancement!

Since the s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings. Are you sure you want to delete this answer? Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.

Once the Flood processes ceased, C began a slow build-up to equilibrium with C—a build-up not yet complete. Who are those "real scientists" who think Carbon dating is used to determine the age of the earth? Most radiocarbon dating today is done using an accelerator mass spectrometeran instrument that directly counts dating agency czech republic numbers of carbon and carbon in a sample. Thermoluminescence is excellent for pottery, for example. Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years.
