Age of the Earth

First let me just give you a philosophical overview as to why the question is disingenuous and you are barking up the wrong tree. Was Richard Leakey correct, did they toss out the fossil, or the theories on early man? No, he was not. Of course, that is because he was taken out of context in that selective quote a favorite creationist tactic. I’ll lecture later on why he said it, but later in the same article, he also admits that he, or someone else could have made a mistake, and they needed to figure it out. Were the first 4 2. Million dates thought to be accurate at the time of their original publication?

Carbon Dating

This technique is widely used on recent artifacts, but teachers should note that this technique will not work on older fossils like those of the dinosaurs which are over 65 million years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharohs among other things.

If the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe. Geologists and paleontologists are highly self-critical, and they have worried for decades about these issues.

Dinosaurs supposedly died out 65 million years ago. Several tests were done by the University of Georgia using accelerator mass spectrometry. The age for all these fossils was found to be less than 50, years 1. This is not predicted by conventional evolutionary theory; and other discoveries have been made concerning dinosaurs which also are not predicted by evolutionary theory such as the discovery of soft tissue in bones that are not or are only partially fossilized.

However, the abstract of the Miller presentation was removed from the website for the conference. If the accepted ages of millions of years for dinosaurs were to be found to be in error, this would be a problem to evolution. The dinosaur dates reported below and discussed in the AOGS paper discussed throughout this article, included triceratops, hadrosaur, allosaurus, and acrocanthasaurs.

Below is a list of some dinosaur fossils and their dated ages from the Miller paper. An apatosaurus was found in late Jurassic strata of the Morrison formation, and excavation was done in and In a triceratops horn was found.

Fossil dating – Molecular clock shows wrong time?

Cells are most susceptible to damage by ionizing radiation when they are dividing. As you might have inferred from this, this means that if the radiation experienced by these cockroaches was consistent over a long period of time, they are going to be significantly more susceptible to problems than the numbers quoted in this article. The above numbers are using specific bursts of radiation over a short span.

More accurate research would then have to be done to see what levels of radiation kill or otherwise will significantly harm the roaches that are currently having their cells divide. Further, ionizing radiation is cumulative, so that would have to be factored in as well.

reasons why you cant trust carbon dating creationist creationism evolution dinosaurs. Since carbon dating measures the amount of carbon still in a fossil, then the date given is not accurate. This is just one of many inaccurate dates given by Carbon dating. Mollusks.

Shop Now Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old. With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth. Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

Basics Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry. Recall that atoms are the basic building blocks of matter. Atoms are made up of much smaller particles called protons, neutrons, and electrons. Protons and neutrons make up the center nucleus of the atom, and electrons form shells around the nucleus.

The number of protons in the nucleus of an atom determines the element. For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons. The number of neutrons in the nucleus can vary in any given type of atom.

Problems with the U-Pb Radioisotope Dating Methods—1. Common Pb

Love-hungry teenagers and archaeologists agree: But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Until this century, relative dating was the only technique for identifying the age of a truly ancient object. By examining the object’s relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.

Though still heavily used, relative dating is now augmented by several modern dating techniques.

the air. Thus, a freshly killed mussel has far less C than a freshly killed something else, which is why the C dating method makes freshwater mussels seem older than they really are.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.

If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found. I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.

Even the creationist accounts that I have read do not adequately treat these issues. At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth.

Everything Worth Knowing About … Scientific Dating Methods

The Theory Carbon 14 is a radioactive isotope of carbon. It is produced in the upper atmosphere by radiation from the sun. Specifically, neutrons hit nitrogen atoms and transmute them to carbon. Land plants, such as trees, get their carbon from carbon dioxide in the air.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

Outlook Other Abstract U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon. A variety of analytical instruments have also now been developed using different micro-sampling techniques coupled with mass spectrometers, thus enabling wide usage of U-Pb radioisotope dating. However, problems remain in the interpretation of the measured Pb isotopic ratios to transform them into ages.

Among them is the presence of non-radiogenic Pb of unknown composition, often referred to as common or initial Pb. There is also primordial Pb that the earth acquired when it formed, its isotopic composition determined as that of troilite in the Canyon Diablo iron meteorite. Subsequently new crustal rocks formed via partial melts from the mantle. So the Pb isotope ratios measured in these rocks today must be interpreted before their U-Pb ages can be calculated. Various methods have been devised to determine this initial or common Pb, but all involve making unprovable assumptions.

Zircon does incorporate initial Pb when it crystallizes. The amount of Pb cannot be measured independently and accurately. It cannot be demonstrated that the initial Pb only consisted of Pb atoms. It cannot be proven that the Pb in apparently cogenetic U- or Th-free minerals is only initial Pb, and that it is identical to the initial Pb in the mineral being dated.

Nevertheless, the ultimate foundation of this U-Pb dating methodology is the assumption that the earth formed from the solar nebula.

Critics have suggested the fossils, which are invisible to the naked eye, are just unusual shapes in the rock and not evidence of life at all. Now, work led by Professor William Schopf, the palaeobiologist who first described the specimens in , has put the matter to rest. The image’s colours have been enhanced after it was sent back to Earth. The tallest of the skeletons uncovered measured at 1.

Radiometric dating is a much misunderstood phenomenon. Evolutionists often misunderstand the method, assuming it gives a definite age for tested samples. Creationists also often misunderstand it, claiming that the process is inaccurate.

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods , at some age which is a lot below the ‘usual’ i. The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old. The particular example you bring up is one of the most famous such cases.

The claims are really quite spectacular, when taken at face value, and therefore should be examined thoroughly. In this answer, I will try to go through this story in great detail, hopefully exposing the reasons why this work is not taken seriously by scientists. The research by Miller et al. A research team from the CRSEF, or Creation Research, Science Education Foundation, led by Hugh Miller, has claimed to have dated dinosaur bones using radiocarbon methods, determining them to be no older than several dozens of thousands of years old.

Why Atheists Don’t Really Exist

Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of. In many instances, absolute dating is considered more accurate than relative dating because it gives a specific time or age to an event or object but with an accuracy that varies with the particular technique and particular object.

Relative dating gives one the ordering of events or gives one the relative ages, i.

C14 dating is very accurate for wood used up to about 4, years ago. This is only because it is well calibrated with objects of known age. Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.

Introduction Radiocarbon, or Carbon dating, was developed by W. It is perhaps one of the most widely used and best known absolute dating methods and has become an indispensable part of an archaeologist’s tool-kit. In , Libby was awarded the Nobel Prize in chemistry for radiocarbon dating. This will enable the reader to gain an appreciation of the advantages and disadvantages of this process.

Is carbon dating applied to the Qur’anic manuscripts? Can radiocarbon dating provide more accurate results than traditional palaeographic techniques and associated methods? We will focus on these questions below. Principles And Practice Carbon has two stable, nonradioactive isotopes: In addition, there are tiny amounts of the unstable radioactive isotope carbon 14C on Earth.

These isotopes are present in the following amounts 12C – In other words, one carbon 14 atom exists in nature for every 1, , , , 12C atoms in a living being. Although 14C takes up only a minute fraction of the carbon content, its presence in carbon-bearing materials form the basis for important geochronological and environmental applications. These energetic neutrons dissociate a nitrogen molecule into atoms and then reacts with these atoms to form 14C. The reaction can be written as:

Radiocarbon Dating of Dinosaur Fossils

What is radiocarbon dating or carbon and how does it work? Radiocarbon Dating All organic matter contains carbon, which is an element. But there are different types of carbon, called isotopes. The most common isotope is carbon or 12 C , which according the article makes up There’s carbon , or 13 C,… which is much rarer, accounting for only 1.

These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay. The decay occurs on a logarithmic scale. For example, the half-life of C is 5, years.

In the first 5, years, the organism will lose half of its C isotopes. In another 5, years, the organism will lose another half of the remaining C isotopes. This process continues over time, with the organism losing half of the remaining C isotopes each 5, years. Radioactive Dating of Fossils Fossils are collected along with rocks that occur from the same strata. These samples are carefully cataloged and analyzed with a mass spectrometer. The mass spectrometer is able to give information about the type and amount of isotopes found in the rock.

Scientists find the ratio of parent isotope to daughter isotope.
