There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset. Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble. As of January, , The oldest rocks found on earth are 4.

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.
Recent research by a creation science group known as RATE Radioisotopes and the Age of The Earth has produced evidence of accelerated rates of decay at some point or points in the past.
June 23rd, Author: Consequently the civilizations of the world naturally and simultaneously started developing near the rivers which initially started flowing due to the melting of glaciers near the Equator e. South India, Sri Lanka and Africa. When populations multiplied, these river waters became insufficient. Therefore some people started travelling from south to north. Such northward migration continued for several centuries and finally when these people from south India reached the banks of Himalayan Rivers, they got climatic conditions conducive to long term development of civilization on the banks of these rivers providing security of water, food and shelter for a very long time.
The Age of the Earth
Design, and Theistic Creationism, only one of which can reflect reality. Six quotations that illustrate the great gulf in beliefs concerning origins of the earth and its life forms: The National Center for Science Education posted a notice about an annual celebration of evolution: Michael Zimmerman, the initiator of the project, writes, ‘Evolution Weekend is an opportunity for serious discussion and reflection on the relationship between religion and science.
One important goal is to elevate the quality of the discussion on this critical topic — to move beyond sound bites. A second critical goal is to demonstrate that religious people from many faiths and locations understand that evolution is sound science and poses no problems for their faith’.

Slowly and painstakingly, geologists have assembled this record into the generalized geologic time scale shown in Figure 1. This was done by observing the relative age sequence of rock units in a given area and determining, from stratigraphic relations, which rock units are younger, which are older, and what assemblages of fossils are contained in each unit.
Using fossils to correlate from area to area, geologists have been able to work out a relative worldwide order of rock formations and to divide the rock record and geologic time into the eras, periods, and epochs shown in Figure 1. The last modification to the geologic time scale of Figure 1 was in the s, before radiometric dating was fully developed, when the Oligocene Epoch was inserted between the Eocene and the Miocene.
Although early stratigraphers could determine the relative order of rock units and fossils, they could only estimate the lengths of time involved by observing the rates of present geologic processes and comparing the rocks produced by those processes with those preserved in the stratigraphic record. With the development of modern radiometric dating methods in the late s and s, it was possible for the first time not only to measure the lengths of the eras, periods, and epochs but also to check the relative order of these geologic time units.
Radiometric dating verified that the relative time scale determined by stratigraphers and paleontologists Figure 1 is absolutely correct, a result that could only have been obtained if both the relative time scale and radiometric dating methods were correct. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.
Radiometric dating has not been applied to just a few selected rocks from the geologic record. Literally many tens of thousands of radiometric age measurements are documented in the scientific literature.
Radioisotopes and the Age of the Earth (RATE)
About this Reference Work This volume provides an overview of 1 the physical and chemical foundations of dating methods and 2 the applications of dating methods in the geological sciences, biology, and archaeology, in almost articles from over international authors. It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields.
No other volume has a similar scope, in terms of methods and applications and particularly time range. Dating methods are used to determine the timing and rate of various processes, such as sedimentation terrestrial and marine , tectonics, volcanism, geomorphological change, cooling rates, crystallization, fluid flow, glaciation, climate change and evolution.
The best documented case of this situation is that of mainland China Watson and Pauly , whose over-reported catches for local waters in the North-west Pacific are inflated by under-reported catches taken by Chinese distant water fleets, which, in the s, operated in the EEZs of over 90 countries, i.

Treat disputed zones i. Maritime limits and boundaries depicted on Sea Around Us maps are not to be considered as an authority on the delimitation of international maritime boundaries. These maps are drawn on the basis of the best information available to us. Where no maritime boundary has been agreed, theoretical equidistance lines have been constructed.
Where a boundary is in dispute, we attempt to show the claims of the respective parties where these are known to us and show areas of overlapping claims. In areas where a maritime boundary has yet to be agreed, it should be emphasized that our maps are not to be taken as the endorsement of one claim over another.

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic Stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria. While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae.
One genus of stromatolite very common in the geologic record is Collenia. The earliest stromatolite of confirmed microbial origin dates to 2. The most widely supported explanation is that stromatolite builders fell victims to grazing creatures the Cambrian substrate revolution , implying that sufficiently complex organisms were common over 1 billion years ago.
Needless to say, creationists who propose such special pleading have never produced any kind of coherent scientific model for how this contrived idea might have been accomplished.
How accurate are carbon-dating methods? All methods of radioactive dating rely on three assumptions that may not necessarily be true: Rate of Decay It is assumed that the rate of decay has remained constant over time. This assumption is backed by numerous scientific studies and is relatively sound. However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.
Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant. Thus radioactive dating relies purely on assumptions.

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.
At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.

His calculations did not account for heat produced via radioactive decay a process then unknown to science or, more significantly, convection inside the Earth, which allows more heat to escape from the interior to warm rocks near the surface. For biologists, even million years seemed much too short to be plausible. In Darwin’s theory of evolution , the process of random heritable variation with cumulative selection requires great durations of time.
According to modern biology, the total evolutionary history from the beginning of life to today has taken place since 3. Huxley , attacked Thomson’s calculations, suggesting they appeared precise in themselves but were based on faulty assumptions. The physicist Hermann von Helmholtz in and astronomer Simon Newcomb in contributed their own calculations of 22 and 18 million years respectively to the debate: However, they assumed that the Sun was only glowing from the heat of its gravitational contraction.
The process of solar nuclear fusion was not yet known to science.
How accurate are Carbon-14 and other radioactive dating methods?
Several Christian ministries promote the idea that the earth is less than 10, years old, which they say comes from the Bible. In reality, the Bible makes no claim as to the age of the earth, although it does establish a minimum age. This page examines some of the history of the controversy—what the Bible actually says and does not say—and the scientific evidence surrounding the age of the earth.
Age of the earth according to the Bible The following is a summary of the biblical evidence presented on this website regarding the age of the earth. For more detailed explanations of each topic, please click on the associated link. History of the age of the earth As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis.
These generally include constancy of decay rate and lack of contamination gain or loss of parent or daughter isotope.
By Eric Hovind on May 5, in Articles , Beginner Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. How Carbon Dating Works Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon This radioactive carbon 14 slowly decays back into normal, stable nitrogen.
Extensive laboratory testing has shown that about half of the C molecules will decay in 5, years. This is called the half-life.
Does carbon dating prove the earth is millions of years old?
Why almost all scientists believe in evolution: It is impossible to prove that the theory of evolution is absolutely true. The theory maintains that plant evolution, animal evolution and the major geological changes to the earth unfolded over billions of years. Thus, the full theory cannot be demonstrated in the laboratory.
Next, God had Adam give names to “all the beasts of the field and all the birds of the air” Genesis 2:
My friends call me Ape Jaw Evan. Click here to read about me and other media myths, frauds, and lies. The Theory of Evolution is not a scientific law or a law of biology. Failure to meet only one challenge proves the law is wrong. This web page will prove that the Theory of Evolution fails many challenges, not simply one. The Theory of Evolution will never become a law of science because it is wrought with errors.
This is why it is called a theory, instead of a law. The process of natural selection is not an evolutionary process. The DNA in plants and animals allows selective breeding to achieve desired results. Dogs are a good example of selective breeding. The DNA in all dogs has many recessive traits. A desired trait can be produced in dogs by selecting dogs with a particular trait to produce offspring with that trait. This specialized selective breeding can continue for generation after generation until a breed of dog is developed.
