How Does Radiocarbon Dating Work? - Instant Egghead #28
Plants talk to each other using an internet of fungus
11 Nov Some of these plants, such as the phantom orchid, get the carbon they need from nearby trees, via the mycelia of fungi that both are connected to. "These experiments show the fungal networks can transport these chemicals in high enough concentrations to affect plant growth,” says Morris, who is now. First, the relative age of a fossil can be determined. Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event. Second, it is possible to determine the numerical age for fossils or earth materials. Numerical ages estimate the date of a geological event . How old does the Bible say the earth is Nowhere in the Bible do we find an exact statement that says precisely how many years old the Earth is. However, the Bible is filled with statements that, if added together, can give us a fairly accurate age for the Earth. You see, in ancient times people did not receive pretty picture.

The question of the age of the earth has produced heated discussions on Internet debate boards, TV, radio, in classrooms, and in many churches, Christian colleges, and seminaries. The primary sides are.
How Do We Know How Old the Earth Is?
The difference is immense! Simply put, it came from the Bible. God gave us something better.
It is similar with the earth. Genesis 1 says that the earth was created on the first day of creation Genesis 1: From there, we can begin to calculate the age of the earth. Adam was created on day 6, so there were five days before him. If we add up the dates from Adam to Abraham, we get about 2, years, using the Masoretic Hebrew text of Genesis 5 and At this point, the first five days are negligible.
Quite a few people have done this calculation using the Masoretic text which is what most English translations are based on and with read article attention to the biblical details, they have arrived at the same time frame of about 6, years, or about B. Two of the most popular, and perhaps best, are a recent work by Dr.
Floyd Jones 4 and a much earlier book by Archbishop James Ussher 5 please click for source The misconception exists that Ussher and Jones were the only ones to arrive at a date of B.
Jones 6 lists several chronologists who have undertaken the task of calculating the age of the earth based on the Bible, and their calculations range from to B. A few are listed in table 2. As you will How Old Does Carbon Hookup Say The Earth Is note from table 2, the dates are not all B. There are several reasons chronologists have different dates, 7 but two primary reasons:. Because of this, the Septuagint adds in extra time.
Though the Samarian and Masoretic texts are much closer, they still have a few differences. Using data from table 2 excluding the Septuagint calculations and including Jones and Ussherthe average date of the creation of the earth is B.
This still yields an average of about 6, years for the age of the earth. Cultures throughout the world have kept track of history as well. From a biblical perspective, we would expect the dates given for creation of the earth to align more closely to the biblical date than billions of years. This is expected since everyone was descended from Noah and scattered from the Tower of Babel.
Another expectation is that there should be some discrepancies about the age of the earth among people as they scattered throughout the world, taking their uninspired records or oral history to different parts of the globe.
The Irish chronology has a date of about B. Even the Mayans had a date for the Flood of B. This meticulous work of many historians should not be ignored. Their dates of only thousands of years are good support for the biblical date of about 6, years, but not for billions of years. Prior to the s, few believed in an old earth. The approximate 6,year age for the earth was challenged only rather recently, beginning in the late 18th century.
These opponents of the biblical chronology essentially left God out of the picture. Three of the old-earth advocates included Comte de Buffon, who thought the earth was at least 75, years old. And Jean Lamarck also proposed long ages. However, the idea of millions of years really took hold in geology when men like Abraham Werner, James Hutton, William Smith, Georges Cuvier, and Charles Lyell used their interpretations of geology as the standard, rather than the Bible.
Werner estimated the age of the earth at about one million years. Smith and Cuvier believed untold ages were needed for the formation of rock layers. From these men and others came the consensus view that the geologic layers were laid down slowly over long periods of time based on the rates at which we see them accumulating today.
Though some, such as Cuvier and Smith, believed in multiple catastrophes separated by long periods of time, the uniformitarian concept became the ruling dogma in geology. Thinking biblically, we can see that the global flood in Genesis 6—8 would wipe away the concept of millions of years, for this Flood would explain massive amounts of fossil layers.
Most Christians fail to realize that a global flood could rip up many of the previous rock layers and redeposit them elsewhere, destroying the previous fragile contents. This would destroy any evidence of alleged millions of years anyway.

So the rock layers can theoretically represent the evidence of either millions of years or a global flood, but not both. Sadly, by abouteven most of the Church had accepted the dogmatic claims of the secular geologists and rejected the global flood and the biblical age of the earth. After Lyell, in read more, Lord Kelvin William Thomson calculated the age of the earth, based on the cooling rate of a molten sphere, at a maximum of about 20—40 million years this was revised from his earlier calculation of million years in But there is growing scientific evidence that radiometric dating methods are completely unreliable.

Christians who have felt compelled to accept the millions of years as fact and try to fit them into the Bible need to become aware of this evidence. Today, secular geologists will allow some catastrophic events into their thinking as an explanation for what they see in the rocks. The age of the earth debate ultimately comes down to this foundational question: Radiometric dating was the culminating factor that led to the belief in billions of years for earth history.
However, radiometric dating methods are not the only uniformitarian methods. Any radiometric dating model or other uniformitarian dating method can and does have problems, as referenced before. All uniformitarian dating methods require assumptions for extrapolating present-day processes back into the past. The assumptions related to radiometric dating can be seen in these questions:.
If the assumptions are truly accurate, then uniformitarian dates should agree with radiometric dating across the board for the same event.
Research has been done to demonstrate that many of the assumptions used in radiometric dating are false. That suggests the mycelia really did transport the toxins. Retrieved May 27, How to Become a Primate Fossil.
Henry Morris compiled a list of 68 uniformitarian estimates for the age of the earth by Christian and secular sources. In one case, the date was uncertain so it was not used in this tally, so the total estimates used were A few on the list had reference to Saturn, the sun, etc.
As you can see from table 6, uniformitarian maximum ages for the earth obtained from other methods are nowhere near the 4. The results from some radiometric dating methods completely undermine those from the source radiometric methods. One such example is carbon 14 C dating. As long as an organism is alive, it takes in 14 C and 12 C from the atmosphere; however, when it dies, the carbon intake stops.
Since 14 C is radioactive decays into 14 Nthe amount of 14 C in a dead organism gets less and less over time. Now, 14 C has a derived half-life of 5, years, so the 14 C in organic material supposedlyyears old should all essentially have decayed into nitrogen.
Coal and diamonds, which are found in or sandwiched between rock layers allegedly millions of years old, have been shown to have 14 C ages of only tens of thousands of years. This shows that these dating methods are completely unreliable and indicates that the presumed assumptions in the methods are erroneous.
Similar kinds of problems are seen in the case of potassium-argon dating, which has been considered one of the most reliable methods.
Andrew Snelling, a geologist, points out several of these problems with potassium-argon, as seen in table 7. These and other examples article source a critical question. If radiometric dating fails to give an accurate date on something of which we do know the true age, then how can it be trusted to give us the correct age for rocks that had no human observers to record when they formed?
It is far more rational to trust the Word of the God who created the world, knows its history perfectly, and has revealed sufficient information in the Bible for us to understand that history and the age of the creation.
Cultures around the world give an age of the earth that confirms what the Bible teaches. Radiometric dates, on the other hand, have been shown to be wildly in error. People complain about The New Answers Book.
