Most people accept the current old-earth OE age estimate of around 4. This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective. This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation. Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept. This challenge is mainly headed by Creationism which teaches a young-earth YE theory. A young earth is considered to be typically just 6, years old since this fits the creation account and some dating deductions from Genesis.
Aristotle thought the earth had existed eternally. Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being.
Within decades observation began overtaking such thinking. In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata.
Potassium-argon dating, method of determining the time of origin of rocks by measuring On the other hand, the abundance of argon in the Earth is relatively small rocks as young as 20, years old have been measured by this method.
See this page in: Hungarian , Russian , Spanish. P eople who ask about carbon 14 C dating usually want to know about the radiometric  dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days?
Christians , by definition, take the statements of Jesus Christ seriously. He said,. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. Carbon has unique properties that are essential for life on Earth. One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon, or 14 C, or radiocarbon.
Carbon is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere.
How Old is Earth, and How Do We Know?
You’ve got two decay products, lead and helium, and they’re giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy. Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods. Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old.
Young Earth creationists tell us that we can’t. After all, it makes the same range of assumptions as other radiometric dating methods, and then.
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.
By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
How Good Are Those Young-Earth Arguments?
Metrics details. Earth scientists have devised many complementary and consistent techniques to estimate the ages of geologic events. Annually deposited layers of sediments or ice document hundreds of thousands of years of continuous Earth history. Gradual rates of mountain building, erosion of mountains, and the motions of tectonic plates imply hundreds of millions of years of change.
believe that the radiometric dating methods prove that the earth is clearly supports the idea of a young earth as described by the Bible.
Carbon 14 is used for this example:, which was put out by Dr. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed. Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p. In another creationist, Robert L.
Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere! The argument may be compared to filling a barrel which has numerous small holes in its sides.

These techniques are somewhat similar to the radiometric methods of dating I shall deal with the positive arguments for a young earth in much less detail.
O ne of the main objections to radiometric dating on the part of young earth creationists is that radiometric ages do not agree with each other or that contamination renders ages meaningless. In fact, the claim is partially true. Early mass spectrometers were not as sensitive as machines today and the methods for separating, cleaning and analysis were less sophisticated. Although ye-creationists like Snelling talk about contamination of isotopic systems as if it were a foreign concept to modern geology, most geochronologists routinely check for possible contamination using a variety of methods.
Creationists have seized upon these discoveries and held them forth as evidence that radiometric dating is inaccurate. But is this the case? If radiometric decay rates are not constant and rocks behave as open systems, it would be the exception, rather than the rule, for ages to agree with one another. Here are a few examples in the recent literature of radiometric age determinations on the same rocks using different isotopic methods a. Not only are their ages similar, but the direction of magnetization in the rocks is also identical and indicates that Oslo, Norway was located at about 30 degrees south at the time.
This is an important consideration.
How accurate are Carbon-14 and other radioactive dating methods?
Creationist’s Blind Dates. The standard scientific estimate is that the universe is about 15 billion years old, the earth about 4. It is important to recognize from the start that there are independent procedures for obtaining each of these estimates, and that the procedures yield ranges of values that overlap. In the case of the universe, estimates can be obtained from astronomical methods or considerations of nuclear reactions.
other young-Earth creationists have never found any rock on Earth that gives an age date of 6, years no matter what age dating method is.
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature. The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.
First, it provides no evidence whatsoever to support their claim that the earth is very young. If the earth were only —10 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far. Where are the data and age calculations that result in a consistent set of ages for all rocks on earth, as well as those from the moon and the meteorites, no greater than 10 years? Glaringly absent, it seems.
Second, it is an approach doomed to failure at the outset. Creationists seem to think that a few examples of incorrect radiometric ages invalidate all of the results of radiometric dating, but such a conclusion is illogical. Even things that work well do not work well all of the time and under all circumstances.
Creation 101: Radiometric Dating and the Age of the Earth
Now there are evidences that explain why isotopic dating methods yield such old on samples that are really only a few thousand years old on a young earth.

Teaching about Radiometric Dating Students, particularly Young-Earth Creationists, may come in with misconceptions about how the age of the Earth and of various parts of the fossil record were determined.
For example, they may assume that the whole geologic timeline is based on radiocarbon dating, which only gives reliable results for dates back to 40, years before present Low, personal communication. Others will argue that decay rates could have changed Wise, , or that God could have changed them, which might result in too-old dates. The former argument is flawed because many radiometric dates are broadly supported by other estimates of change, such as tree rings and varved sediments for radiocarbon with some discrepancies, but still leaving the Earth far more than 6, years old.
The second is not a scientific argument. If supernatural forces are changing the laws of physics while we’re not looking, no form of science, “creation science” or otherwise, can prove or disprove it.
Rock of Ages, Ages of Rock
Jul 7. Posted by Paul Braterman. Can we trust radiocarbon dating? After all, it makes the same range of assumptions as other radiometric dating methods, and then some. Other methods benefit from internal checks or duplications, which in the case of radiocarbon dating are generally absent. There are numerous cases where it appears to give absurdly old ages for young material, while apparent ages of a few tens of thousands of years are regularly reported for material known on other evidence to be millions of years old.
The topic of radiometric dating and other dating methods has received some of the most vicious attacks by young earth creation science theorists. However, none of the criticisms of young earth creationists have any scientific merit. Radiometric dating remains a reliable scientific method.

Teaching about Radiometric Dating
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known. Some do not change with time and form stable isotopes i.
The unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes. Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.
A survey of various dating methods and age indicators is given, including Lord Kelvin’s result involving the Earth’s thermal gradient, various.
Comparisons between the observed abundance of certain naturally occurring radioactive isotopes and their decay products, using known decay rates, can be used to measure timescales ranging from before the birth of the Earth to the present. For example measuring the ratio of stable and radioactive isotopes in meteorites can give us information on their history and provenance. Radiometric dating techiques were pioneered by Bertram Boltwood in , when he was the first to establish the age of rocks by measuring the decay products of the uranium to lead.
Carbon is the basic building block of organic compounds and is therefore an essential part of life on earth. Natural carbon contains two stable isotopes 12 C Radiocarbon dating was developed in the s, with Willard Libby receiving the Nobel Prize in chemistry for the use of 14 C to determine age in archaeology, geology, geophysics and many other branches of science. For many years it was assumed that the content of 14 C in the atmosphere was constant.
We now know that the Earth and solar magnetic fields are changing in time. This means that the flux of cosmic rays impinging on the atmosphere varies, and therefore so does the 14 C production rate. That makes it necessary to calibrate the 14 C dates according to other techniques. One such technique is the dendrochronology , or tree-ring dating. The dendrochronology involves obtaining a horizontal cross-section of the main trunk of a tree and analysing the visible rings caused by the natural plant growth.
