Today, though, a friend of mine shared this youtube video from AiG about radiometric dating, and why it is supposedly unreliable for determining the age of rocks. Now, I am not a scientist, and most scientific discussion makes my eyes glaze over. My brain is wired for literature, poetry, and Biblical Studies. As I watched this short video, though, a few thoughts popped into my head that I just have to share. First, take minutes and watch for yourself. Up to that mark, I was somewhat surprised: AiG gave a straightforward explanation regarding radiometric dating and half-life. Thanks AiG, for admitting that and for giving scientists a certain amount of credit and respect.

Many get fed up with Ken Ham and Answers in Genesis continually misrepresented normal science. This is a good summary of why his recent porkies are pure Ham. Isochron dating bypasses the necessity of knowing the quantity of initial daughter product in the rock by not using that value in the computation.

Although the difference is slight, the implications could help determine how our solar system evolved. The air on Earth contains three different kinds of oxygen atoms which are differentiated by the number of neutrons they contain. Nearly percent of oxygen atoms in the solar system are composed of O, but there are also tiny amounts of more exotic oxygen isotopes called O and O Researchers studying the oxygen of Genesis samples found that the percentage of O in the sun is slightly higher than on Earth or on other terrestrial planets.
The other isotopes’ percentages were slightly lower. Another paper detailed differences between the sun and planets in the element nitrogen. Like oxygen, nitrogen has one isotope, N, that makes up nearly percent of the atoms in the solar system, but there is also a tiny amount of N

The chronological figures related to genealogies in Scripture add up to approximately 6, years since the creation of described in Genesis. Many creationists consider these figures to be relatively complete, and thus the Earth is considered to be about 6, to perhaps as much as 10, years old. Biblical scholars do not agree on whether the Bible indicates that the planet Earth was created at the beginning of creation week or if it was already present as a lifeless, wet and dark planet here prior to creation week.
The Bible does not give an age for the Earth, nor is any theological point drawn from the age of the Earth, so it may not be as important as some of the other issues. Most scientists believe the Earth is about 4. This figure is based on radiometric dating. Some creationists have attempted to reconcile this figure with the creation in Genesis by proposing that the rocky, lifeless planet was created long ago perhaps 4.
Other creationists hold that the planet itself was created during creation week, perhaps early in the first day of creation.
The Age of the Earth
By Kirk Reynolds. The global flood as described in the Bible has been attacked by Christians as well as non-Christians. Those Christians who do not hold to a literal reading of Genesis are willing to believe in the old age of the earth as proposed by evolution. This belief states that the universe came into existence approximately 12 billion years ago through the Big Bang. There are several theories of creation based on this evolutionary timeline, such as Progressive Creation, Gap Theory, Framework Hypothesis, and Theistic Evolution.
Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements. The starting isotope is called the.
Most people envision radiometric dating by analogy to sand grains in an hourglass: the grains fall at a known rate, so that the ratio of grains between top and bottom is always proportional to the time elapsed. In principle, the potassium-argon K-Ar decay system is no different. Of the naturally occurring isotopes of potassium, 40K is radioactive and decays into 40Ar at a precisely known rate, so that the ratio of 40K to 40Ar in minerals is always proportional to the time elapsed since the mineral formed [ Note: 40K is a potassium atom with an atomic mass of 40 units; 40Ar is an argon atom with an atomic mass of 40 units].
In theory, therefore, we can estimate the age of the mineral simply by measuring the relative abundances of each isotope. Over the past 60 years, potassium-argon dating has been extremely successful, particularly in dating the ocean floor and volcanic eruptions. K-Ar ages increase away from spreading ridges, just as we might expect, and recent volcanic eruptions yield very young dates, while older volcanic rocks yield very old dates.
Though we know that K-Ar dating works and is generally quite accurate, however, the method does have several limitations. First of all, the dating technique assumes that upon cooling, potassium-bearing minerals contain a very tiny amount of argon an amount equal to that in the atmosphere. While this assumption holds true in the vast majority of cases, excess argon can occasionally be trapped in the mineral when it crystallizes, causing the K-Ar model age to be a few hundred thousand to a few million years older than the actual cooling age.
How accurate are Carbon-14 and other radioactive dating methods?
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods.
This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.
Are radiometric methods of dating rocks and fossils reliable? What evidences support a young age for the earth? Where did the idea of “millions of years” come.
Six research scientists with specialized training in Geology, Geophysics, Astrophysics, and Physics met to report on research completed over the past year. They also discussed plans for future activities. An initial approach taken by some of the investigators is to explore models for accelerated rates of decay of radioisotopes during Creation, the Fall, or the Flood. Several sources of data suggest that significant quantities of radioactive decay have occurred during the history of the earth and cosmos.
The conventional age model assumes that this decay has occurred over billions of years at constant rates rather than in concentrated episodes over short periods of time. Some of the RATE researchers believe other explanations that do not require accelerated decay may be the answer, such as the geochemical distribution of elements.
If you are a seller for this product, would you like to suggest updates through seller support? Did humans really evolve from ape-like creatures? Have scientists found fossils of the missing link? What about the similarity between human an chimp DNA? What about the Neanderthal? These and other questions are answered in this Pocket Guide to Apemen.
Yet the genealogies of Genesis 5 and 11 constrain the age of the earth to approximately This implies that conventional radioisotope dating of rocks based on there seems to be nothing to suggest otherwise—the answer seems to be yes.
Flaws in Dating? Roland Watts. Matt’s style is to post a link from a creationist web site, usually Answers in Genesis, which contains the usual bunkum that has been refuted many times then to refuse to acknowledge any rebuttals. Below is a critical look at one of Matt’s typical posts. In this one Matt airs the old creationist claim that the dating system is flawed.
On March 10 you posted a link under the heading “Flaws in Dating”.
The RationalMedia Foundation board of trustees election is completed and the results are posted. Thank you for your interest and participation! Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have decayed. Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.
The time that it takes for half of a sample to decay is known as the half life of the isotope. Some isotopes have half lives longer than the present age of the universe , but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
I’m not going to try to defend these bad date answers. I cahow without the original articles. The creation genesis author is correct in calling this the “dating game.
Science in Christian Perspective. Radiometric Dating. A Christian Perspective. Roger C. Wiens has a PhD in Physics, with a minor in Geology. His PhD thesis was on isotope ratios in meteorites, including surface exposure dating. Radiometric dating–the process of determining the age of rocks from the decay of their radioactive elements–has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago. Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers. Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

The following comprises a series of essays written in response to a discussion held on the Message Board of this web site. The discussion, between a young creationist, Rob, and several other regular contributors, eventually came to the issue of radio isotope dating. Rob mentioned that Steve Austin’s Grand Canyon dating experiment cast doubt on the viability of absolute dating systems. Naturally the notion was rebuffed and respondents pointed to articles heavily critical of the YEC experiment.
