Outlook Other In the ongoing war between creation and evolution, Christians are always looking for the strongest evidence for creation. Most well-meaning, informed creationists would agree in principle that things which are not carefully documented and researched should not be used. But in practice, many of them are very quick to accept the sorts of facts mentioned here, without asking too many questions. Evidence Creationists and evolutionists, Christians and non-Christians, all have the same facts.
The difference is in the way we all interpret the facts. And why do we interpret facts differently?
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.
They are both forms allotropes of carbon. Most carbon atoms are 12 times heavier than hydrogen 12C , about one in is 13 times heavier 13C , and one in a trillion is 14 times heavier 14C. Of these different types isotopes of carbon, 14C is called radiocarbon, because it is radioactive—it breaks down over time. Radiocarbon dating wikimedia commons The famous Hope Diamond which was found about four centuries ago.
Some try to measure age by how much 14C has decayed. Many people think that radiocarbon dating proves billions of years. After two half lives, a quarter is left; after three half lives, only an eighth; after 10 half lives, less than a thousandth is left. But this is not what we find, even with very sensitive 14C detectors. Diamond requires very high pressure to form—pressure found naturally on earth only deep below the surface.
Thus they probably formed at a depth of — km. Geologists believe that the ones we find must have been transported supersonically 5 to the surface, in extremely violent eruptions through volcanic pipes. Some are found in these pipes, such as kimberlites, while other diamonds were liberated by water erosion and deposited elsewhere called alluvial diamonds.
These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.
Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried.
Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable. Unlike any other method, uranium-lead has a natural cross-check built into it that shows when nature has tampered with the evidence.
See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C 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. 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. We will deal with carbon dating first and then with the other dating methods.
Creation Evidence and Evolution Myth
Share by Mail The question of the meaning and proper interpretation of the early chapters of Genesis is one of the most heated subjects in Christendom today. Few other topics have evoked such polarised opinion and division. The diversity of views on Genesis, even among the most learned of exegetes and scholars, is staggering. While one extreme insists that the days of Genesis must strictly be interpreted as seven consecutive hour periods thus rendering the earth very young indeed — in the order of thousands, and not millions or billions, of years old , at the other extreme lies the notion that the early chapters of Genesis are devoid of any historical content at all.
There is a plethora of competing views which reside in the middle of those polar extremes: In this article, I attempt to show that, while it is possible to interpret the book of Genesis in light of a young earth, there is no Biblical mandate for this conclusion:

Leibnitz reworked Descartes’s cosmogony. Protogea was published much later in An essay toward a Natural History of the Earth. Woodward came down fairly strongly for the view that the flood was an act of God that could not be accounted for by normal physical processes. He also postulated hydrological sorting to account for the ordering of fossils. Whiston added comets to Burnet’s cosmogony as the source of the waters of the flood.
Lectures and Discourse of Earthquakes and Subterranean Eruptions. Hooke believed that the fossils were the remains of extinct species and could not be accounted for by the Flood. Using Descartes’s cosmology, the assumption that the earth was once entirely flooded, and the observation that the sea level was dropping three inches per century near his home, he calculated the age of the earth to be greater than 2 billion years.
Observation sur la Formation des Montagnards Pallas made extensive observations of Russian mountains. He observed the results of processes that acted on mountains, e. He argued for occasional catastrophic events as an origin for mountain building. He himself was suspicious that this was much too young and, in manuscripts published after his death, suggested longer chronologies, including one estimate of nearly 3 billion years.

Feb 12, · Direct radiometric dating of dinosaur bones using the U-Pb method, and ICR’s attempt to avoid the issue Well, they’ve finally done it. In a Geology article published last month, Fassett et al. () described their application of the Uranium-Lead (U-Pb) radiometric dating .
Australopithecus africanus — The word “Australopithecus” means “southern ape. Raymond Dart, professor of anatomy at Witwatersrand University in Johannesburg, was the first to study these fossils. In at Taung in South Africa, Dart discovered a fossil skull consisting of a full face, teeth and jaws, and an endocranial cast of the brain. The brain size was cc. Its age is currently felt to be around two to three million years old.
Dart was convinced that some teeth were man-like and thus concluded a transition between apes and man. His opinions on the matter of this particular skull were largely scorned by the scientists of this time who considered it nothing more than a young chimpanzee now considered to be about three years of age. The skull was soon known derisively as “Dart’s baby. With Piltdown Man’s human cranium and apelike jaw, it was hard to reconcile it to the Taung Child.
Although Dart gave up fossil hunting for some time, all was not lost. Years after the discovery of the “Taungs child”, as it is known today, Dart and Broom found other Australopithecines at Kromdraii, Swartkrans and Makapansgat. These finds of similar creatures seemed to vindicate Dart and Broom, and the scientific community again accepted their finds as they do today.
These new fossil Australopithecines seemed to show two parallel lines of development, one being a small “gracile” slender type and the other a larger “robust” type. Much controversy has existed regarding these types and some investigators, including Richard Leakey, have concluded that they represent merely the male and female of the same species while others say the gracile form, which is believed to be older, evolved into the robust form.

And that means more damage from bad copies of DNA and more pollution, and more damage. People years ago had damaged genes. Why do you think people had genetic diseases, like hemophilia?
Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over billion years ago with routine precisions in the –1 percent range. The.
Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist.
Social and Centralized WordPress, Drupal, and the custom CMS solutions of the world are all independent, non-connected instances that each need to be updated individually. There are over 87 million instances of WordPress alone in the world, and each security upgrade, feature update, and every other single thing has to be updated for each site individually. By contrast, RebelMouse is a social, centralized platform built to keep up with the speed of the tech giants.
Our updates are pushed out to all of our sites at once and sometimes even multiple times a day with content creation tools integrated directly into social APIs. We can get clients off of clunky CMSs and into the future in a matter of days. We iterate with the times and tell you what’s changing in the world, how we’ve reacted to it, and how it’s built into the updates you get from the platform. Our creative agency team trains your teams or takes on special projects.
And it doesn’t take months, it takes hours or days.
Changing Views of the History of the Earth
Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago. It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present.
If I hope to accomplish anything, it will be to simply encourage critical thinking. One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position.
Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute.
In dating: Uranium–lead method. As each dating method was developed, tested, and improved, mainly since , a vast body of knowledge about the behaviour of different isotopic systems under different geologic conditions has evolved.
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.
