How Old Is The Earth? How old is the Earth? Scientists think that the Earth is 4. Coincidentally, this is the same age as the rest of the planets in the Solar System, as well as the Sun. In the early Solar System, all of the planets formed in the solar nebula; the remnants left over from the formation of the Sun. Small particles of dust collected together into larger and larger objects — pebbles, rocks, boulders, etc — until there were many planetoids in the Solar System.

Flaws in dating the earth as ancient

Continental Drift The Age of the Earth: Part Two The theory of Continental Drift is one of the primary “evidences” that is used by evolution believers to promote the belief in an old earth. The theory goes like this:

G. Dalrymple has done a wonderful job in writing such a technical work on the history and direct data for the current estimate of the age of the Earth being Billion years old and the Universe being 7 – .

For example, back in , Lord Kelvin calculated how long Earth might have taken to cool from its original molten state. He concluded that Earth was born 20 to million years ago. Their message proved difficult to decipher. How old is Earth? However, from working with layer upon layer of rock laid down on Earth over long time spans, early 20th century scientists came to believe Earth not millions of years old — but billions of years old.

Modern radiometric dating methods came into prominence in the late s and s. These methods focus on the decay of atoms of one chemical element into another. They led to the discovery that certain very heavy elements could decay into lighter elements — such as uranium decaying into lead. This work gave rise to a process known as radiometric dating. This technique is based on a comparison between the measured amount of a naturally occurring radioactive element and its decay products, assuming a constant rate of decay — known as a half-life.

Over the decades of the 20th century, scientists documented tens of thousands of radiometric age measurements. Likewise, scientists use radiometric dating to determine the ages of moon rocks, obtained by astronauts. Taken together, these methods give results that suggest an age for our Earth, meteorites, the moon — and by inference our entire solar system — of 4.

Clearly visible in the canyon walls are the light-colored granites, such as the Zoroaster Granite, which are stark against the darker, folded strata of the Vishnu Schist and the other metamorphic rock units of the Granite Gorge Metamorphic Suite1 see lowest purple and green shading in diagram. These are former sedimentary and volcanic strata that have been transformed by heat and pressure, possibly during the intense upheavals when the dry land was formed on Day 3 of Creation Week.

These were originally basalt lava flows several meters to tens of meters thick. In some outcrops pillow structures have been preserved, testimony to the basalt lavas having originally erupted and flowed under water onto the Creation Week ocean floor. Metamorphic rocks are not always easy to date using radio-isotopes.

PROCEDURE A:! Using Cross Sections 1 and 2, determine the sequence of events and order them from oldest to most recent on the Report Sheet. In addition to determining the relative age of .

Reference to a case where the given method did not work This is perhaps the most common objection of all. Creationists point to instances where a given method produced a result that is clearly wrong, and then argue that therefore all such dates may be ignored. Such an argument fails on two counts: First, an instance where a method fails to work does not imply that it does not ever work.

The question is not whether there are “undatable” objects, but rather whether or not all objects cannot be dated by a given method. The fact that one wristwatch has failed to keep time properly cannot be used as a justification for discarding all watches. How many creationists would see the same time on five different clocks and then feel free to ignore it?

Yet, when five radiometric dating methods agree on the age of one of the Earth’s oldest rock formations Dalrymple , p. The claim that the methods produce bad results essentially at random does not explain why these “bad results” are so consistently in line with mainstream science. Claims that the assumptions of a method may be violated Certain requirements are involved with all radiometric dating methods.

These generally include constancy of decay rate and lack of contamination gain or loss of parent or daughter isotope. Creationists often attack these requirements as “unjustified assumptions,” though they are really neither “unjustified” nor “assumptions” in most cases. Rates of radiometric decay the ones relevant to radiometric dating are thought to be based on rather fundamental properties of matter, such as the probability per unit time that a certain particle can “tunnel” out of the nucleus of the atom.

Accuracy of Fossils and Dating Methods

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.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution.

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 crucial point here is: Accepted Dating Methods Here we outline some dating methods , both absolute and relative, that are widely accepted and used by the scientific community.

Dating methods must also rely on another kind of science called historical science. Historical science cannot be observed. Determining the conditions present when a rock first formed can only be studied through historical science. Determining how the environment might have affected a rock also falls under historical science.

How Science Figured Out the Age of Earth. For centuries scholars sought to determine Earth’s age, but the answer had to wait for careful geologic observation, isotopic analyses of the elements.

Astronomy Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers. Using the known rate of change in radio-active elements radiometric dating , some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.

Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole: Introduction Astronomers and geologists have determined that the universe and Earth are billions of years old. This conclusion is not based on just one measurement or one calculation, but on many types of evidence. Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under further reading.

These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10, years. In years of drought, the tree grows less quickly so the ring is narrower; in good growing seasons the ring is thicker. By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate. This method can even be used on dead trees that fell in a forest long ago.

For example, the last rings in the dead tree might match up with rings early in the life of the living tree, so the two trees together can count back many years. In this way, multiple trees can be used to build a master chronology for a forested region.

Radiometric Dating and the Geological Time Scale

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.

A lot! Since Darwin died in , findings from many fields have confirmed and greatly expanded on his ideas. We’ve learned that Earth is old enough for all known species to have evolved. We’ve discovered DNA, which confirms that all organisms are related to one another.

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. In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil. This position came to be known as uniformitarianism, but within it we must distinguish between uniformity of natural law which nearly all of us would accept and the increasingly questionable assumptions of uniformity of process, uniformity of rate and uniformity of outcome.

That is the background to the intellectual drama being played out in this series of papers. It is a drama consisting of a prologue and three acts, complex characters, and no clear heroes or villains. We, of course, know the final outcome, but we should not let that influence our appreciation of the story as it unfolds. Even less should we let that knowledge influence our judgment of the players, acting as they did in their own time, constrained by the concepts and data then available.

One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists. Most notable is William Thomson, ennobled to become Lord Kelvin in , whose theories make up an entire section of this collection. He was one of the dominant physicists of his time, the Age of Steam. His achievements ran from helping formulate the laws of thermodynamics to advising on the first transatlantic telegraph cable.

Tools are objects that make our lives easier. A computer or smart phone are examples of modern-day tools. Paleolithic is a word that comes from the two Greek words palaios, meaning old, and lithos, meaning stone. Using a hammer stone for flaking. Which stone do you think is harder, the object stone, or the hammer stone? The first stone tools were used to meet people’s three basic needs of food, shelter, and clothing.

A Radiometric Dating Resource List Tim Thompson has collected a large set of links to web pages that discuss radiometric dating techniques and the age of the earth controversy.

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. In theory it would never totally disappear, but after about 5 half-lives the difference is not measurable with any degree of accuracy.

Frequently Asked Questions

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.

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. It turns out that both assumptions are false. Incomplete genealogies Biblical Genealogies Although Archbishop Ussher assumed the Genesis genealogies were complete, it is clear from the rest of the Bible that those genealogies were telescoped some names were left out for the sake of brevity , which is common in biblical genealogies but rare in modern genealogies.

Similarly, the key genealogical terms such as “son” and “father” have much broader meanings in Hebrew than their corresponding English words. The Hebrew word translated “son” can also have the meaning of “grandson,” “great grandson,” “descendant,” etc.
