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. Archbishop Ussher took the genealogies of Genesis, assuming they were complete, and calculated all the years to arrive at a date for the creation of the earth on Sunday, October 23, B. There are a number of other assumptions implicit in the calculation. The first, and foremost, assumption is that the genealogies of Genesis are complete, from father to son throughout the entire course of human existence. The second assumption is that the Genesis creation “days” were exactly hours in length.

Some reminders An element consist of one type of atom only. Therefore, elements are the simplest substances that we can use and investigate in chemistry because an element cannot be split into other substances unlike compounds. Each element has identical atoms except for isotopes, different numbers of neutrons – explained later which are physically and chemically identical and each element has its own unique physical and chemical properties. Ever element has its own unique chemical symbol which is used to denote elements in the periodic table, in chemical formulae and chemical equations e.

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: 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.

The International History Project Date: Archaeology studies past human behavior through the examination of material remains of previous human societies. These remains include the fossils preserved bones of humans, food remains, the ruins of buildings, and human artifacts—items such as tools, pottery, and jewelry.
From their studies, archaeologists attempt to reconstruct past ways of life. Archaeology is an important field of anthropology, which is the broad study of human culture and biology.
Overview: The theory of evolution describes an earth that is about billion years old. But many creation scientists interpret the Genesis account of creation as requiring an earth that is only 6, to 10, years of are numerous indicators that the earth was in existence billions of years ago.
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.

Alternating patterns of distinct laminae are commonly identified within glacial lake deposits and are generally interpreted in the following way: However, there is actually no empirical evidence to back the claim that varves form as annual deposits over extended periods of time. It appears then, that claiming a varve is an annual event is an assumption in itself; one steeped in uniformitarian thought, but not reality.

Over the last 40 years, there has been a discernible increase in the number of scholars who have focused their research on early industrial organizations, a field of study that has come to be known as Archaeotechnology. Archaeologists have conducted fieldwork geared to the study of ancient technologies in a cultural context and have drawn on the laboratory analyses developed by materials scientists as one portion of their interpretive program.

Mineralogy As a discipline, mineralogy has had close historical ties with geology. Minerals as basic constituents of rocks and ore deposits are obviously an integral aspect of geology. The problems and techniques of mineralogy, however, are distinct in many respects from those of the rest of geology, with the result that mineralogy has grown to be a large, complex discipline in itself. Nepheline greasy light gray , sodalite blue , cancrinite yellow , feldspar white , and ferromagnesian minerals black in an alkalic syenite from Litchfield, Maine, U.
About 3, distinct mineral species are recognized, but relatively few are important in the kinds of rocks that are abundant in the outer part of the Earth. Thus a few minerals such as the feldspars, quartz, and mica are the essential ingredients in granite and its near relatives.

What is radiocarbon dating? This isotope lets scientists learn the ages of once-living things. Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens — for example, wooden archaeological artifacts or ancient human remains — from the distant past. It can be used on objects as old as about 62, years. What is an isotope? To understand radiocarbon dating, you first have to understand the word isotope.
An isotope is what scientists call two or more forms of the same element. But they still have the same chemical properties. Atoms of the same element that have different numbers of neutrons are called isotopes. Radiocarbon dating uses isotopes of the element carbon. Radiocarbon dating uses carbon isotopes.
Dear Science: How do we know how old the Earth is?
At higher temperatures, CO 2 has poor solubility in water, which means there is less CO 2 available for the photosynthetic reactions. The enrichment of bone 13 C also implies that excreted material is depleted in 13 C relative to the diet. This increase in 14 C concentration almost exactly cancels out the decrease caused by the upwelling of water containing old, and hence 14 C depleted, carbon from the deep ocean, so that direct measurements of 14 C radiation are similar to measurements for the rest of the biosphere.
Correcting for isotopic fractionation, as is done for all radiocarbon dates to allow comparison between results from different parts of the biosphere, gives an apparent age of about years for ocean surface water. The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator.
Amino Acid Dating Introduction. Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself.
For millennia, humans assumed that the Earth was about as old as we were. The “begats” in the Bible were another source for estimates: In the 17th century, Ireland’s Archbishop James Ussher reconstructed the genealogy of biblical figures and declared that Earth was created at 6 p. Scientists now know the Earth is actually 4. The modern effort to understand the age of the planet started with Nicholas Steno , a Danish anatomist and geologist who was among the first to realize that fossils are the remains of living creatures.
Where do old spacecraft go when they die? Not only was the Earth not young, but it was not static, Hutton said. Others looked at the average rate of sedimentation and concluded it would take anywhere from 3 million to 1. Why do we love our pets? Here’s how that works: For example, half of a given batch of uranium will decay into lead every million to 4.

In this work we augment data from previous investigations on petrography and mineral compositions, mid-IR spectroscopy, and oxygen isotope compositions of NWA , and add constraints from Cr and Ti isotope compositions on the provenance of its parent body. In addition, we identify and discuss notable similarities between NWA and clasts of a rare xenolithic lithology found in polymict ureilites.
Modeling of trace elements in plagioclase suggests that this melt formed by fractional melting or multi-stage igneous evolution. A subsequent event likely impact resulted in plagioclase being substantially remelted, reacting with a small amount of pyroxene, and recrystallizing with a distinctive texture. The bulk oxygen isotope composition of NWA plots in the range of ureilites on the CCAM line, and also on a mass-dependent fractionation line extended from acapulcoites.
In terms of all these properties, NWA is unlike any known achondrite. These clasts are probably xenolithic in polymict ureilites, and could be pieces of NWA like meteorites. Using constraints from chromium, titanium and oxygen isotopes, we discuss two possible models for the provenance of the NWA parent body:

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.
Feather structure of a blue-and-yellow macaw Budgerigar feather, magnified, showing interlocking barbules Feathers are among the most complex integumentary appendages found in vertebrates and are formed in tiny follicles in the epidermis , or outer skin layer, that produce keratin proteins. Flight feather and Down feather There are two basic types of feather: The pennaceous feathers are vaned feathers. Also called contour feathers, pennaceous feathers arise from tracts and cover the entire body.

Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the “radiocarbon age”, which is the age in “radiocarbon years” of the sample: Radiocarbon ages are still calculated using this half-life, and are known as “Conventional Radiocarbon Age”.
Since the calibration curve IntCal also reports past atmospheric 14 C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age. When a date is quoted, the reader should be aware that if it is an uncalibrated date a term used for dates given in radiocarbon years it may differ substantially from the best estimate of the actual calendar date, both because it uses the wrong value for the half-life of 14 C, and because no correction calibration has been applied for the historical variation of 14 C in the atmosphere over time.
The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the 14 C generated by cosmic rays to fully mix with them. This affects the ratio of 14 C to 12 C in the different reservoirs, and hence the radiocarbon ages of samples that originated in each reservoir.
