While most of us rely on calendars to track seasons and years, God gave us other markers of the passage of time. For instance, every year trees really do grow a fresh layer of cells on their outer trunks—tree rings. If we count up the rings, we can calculate how old the tree is, right? Each season, rains wash silt onto the bottoms of lakes.

The content of the layers looks different in the spring and fall. So we can just count up the layers and know how long the lake has been there, right? Polar ice sheets add new layers each winter, too. The snow never completely melts in the summer and is covered by a new blanket of snow the following winter. Just count up the layers, and you know how long snow has been falling near the poles, right? Secular scientists believe these layers clearly mark the passage of time and date the earth—whether rings in trees, sediment layers on lake floors called varvesor layering in the ice sheets.

These dating methods seem well founded and Tree ring dating creation because we can observe these seasonal processes happening today. Based on these dating methods, old-earth proponents have constructed chronologies from tree rings they claim go back at least 12, years, lake-floor layers representing 50, years, and ice layers going backyears. The Biblein contrast, indicates that earth is only about 6, years old. Absolutely not, because Godwho never lies, has given us His eyewitness of the creation of the universe and all it contains. When secular scientists use these dating methods, they generally assume that the seasonal processes and conditions we observe today have always been the same.

They also ignore the global cataclysmic impact of the biblical Flood—just as the Apostle Peter predicted modern-day scoffers would 2 Peter —6. Dating tree rings is not as simple as it might seem. Several factors determine the growth rate of trees and the width of their growth rings—the soils, altitude, water table, climate, seasons, and weather. Droughts, fires, and periods of abnormally high rainfall will impact the growth pattern of tree rings, so a tree will not always have one growth ring per year.

Dendrochronology is the technical term for the science of counting the growth rings of trees to estimate the passage of years. They search for buried trees and the beams of timbers in ancient buildings. If they know when the tree was cut down for Tree ring dating creation building say, BC and count the of rings in the tree say,they logically conclude that the tree started growing years before it was cut down thus dating the first growth of the now-dead tree to BC.

This method allows scientists to measure the passage of time a lot farther back than the lifespans of living trees. Or so the theory goes. Scientists must visually compare the appearance of growth rings, noting where some rings appear thicker or thinner. They then match the patterns in dead trees to other trees. They limit their study to one tree species. In this way, scientists establish a hypothetical series of rings, some thin and some thick, going back thousands of years for each species. This is called a master chronology, or timeline, for the species. Whenever scientists find a new log or beam, they can theoretically match the ring patterns in that beam to their hypothetical series.

Yet this involves massive layers of questionable interpretation. There can be major variations from tree to tree in a forest and, accordingly, in the wooden beams used to build houses. Bristlecone pines are hardy trees living high in the western mountains of the US. Some are claimed to be among the oldest living things on earth. They use radiocarbon 14 C dating of growth rings to obtain their approximate age. Then they match this information to the associated pattern of rings in the master tree-ring chronology.

However, ironically, radiocarbon dating is calibrated and corrected using tree-ring chronologies. So conclusions about tree-ring ages depend on radiocarbon dating, which depends on tree rings, which depends on radiocarbon dating.

Neither tree-ring counting nor radiocarbon dating is conclusive alone. The most famous tree-ring chronology is derived from bristlecone pines, which are found in isolated groves at high mountain altitudes in the US Southwest. The trees grow very slowly in dry, limy soils under harsh, cold, and windy weather conditions. Yet they are highly resilient and long-lived.

Their wood is extremely durable, which makes them valuable for dating back a long time. But their growth rings are very thin, making them hard to count. It is named Methuselah and is touted as being 4, years old.

Scientists claim that other trees in secret locations nearby are even older. The bristlecone pine tree-ring chronology was first constructed in Initially researchers dated it back 7, years, but they have extended its age back over 9, years. One problem: the living trees for only 1, years of the chronology, and the whole chronology depends on the accuracy of only two specimens—one living and one dead—where the growth rings appear to overlap see diagram.

In the scientists who made the master tree-ring chronology relied on a data set of radiocarbon 14 C measurements from a collection of bristlecone pine wood samples. But it is well known that the 14 C content of the atmosphere has varied considerably in the past because of climate changes and fluctuations in the amount of cosmic-ray radiation reaching the earth. For example, periods of low Tree ring dating creation activity would dilute the radioactive carbon 14 C in the tree rings, making the ages appear much greater than they really are. As we saw earlier, tree-ring dating depends on subjective visual cross-dating, augmented by radiocarbon dating.

So tree-ring dating relies on radiocarbon dating, while radiocarbon dating has been corrected using tree-ring dating! In the world of logic, that is called circular reasoning—a person uses one assumption to prove another assumption, but neither has an unimpeachable, independent basis of measurement. Only two living trees appear in the tree-ring chronology for bristlecone pines, and they go back only 1, years. Any mistake in lining up those trees with the next ones undermines the whole chronology.

Mistakes in lining up other trees in the series would also ruin the whole chronology. At the bottom of still bodies of water, such as lakes, are layers of deposits called varves. Each varve has two different kinds of layers technically, laminaeone assumed to have been deposited over the summer and the other deposited in the winter.

These grains washed into the lake when spring rains rushed across the landscape and picked up coarse, heavy sand and dirt.

Varve dating has a problem similar to tree-ring dating. It is based on the assumption that the pattern and rate of lake deposits have continued in the same way throughout the past. Those who measure varves must also assume that all the layers are indeed varves. Yet another phenomenon can produce similar. Rhythmites are thin laminae from natural catastrophes that produce a rhythmic ebb and flow of rushing water. Rhythmites are nearly indistinguishable from varves. A single event, such as a dam break or slow-moving hurricane, can deposit a series of many sedimentary layers.

Huge amounts of water can rapidly deposit many alternating laminae, each with distinctive features, in a single week or in hours, in the case of a dam break. Helens on May 18, Landslides, mudflows, steam water, falling volcanic ash, and volcanic ash flowing on the ground deposited a sequence of sediment layers up to feet thick near the volcano.

The most surprising accumulations resulted from several slurries of ash that moved from the volcano at up to 90 miles per hour. These deposits were filled with different layers, including fine volcanic ash beds ranging in thickness from a fraction of an inch to three feet. Each bed was laid in just a few seconds to several minutes.

One of these was a foot-thick layered deposit that accumulated in only three hours on June 12, It consisted of many thin laminae in an alternating pattern of fine-grained and coarse-grained layers, similar to varves. But these were not deposited by alternating conditions; instead they were deposited all at once from the same fast-moving slurries. Though volcanic ash slurries behave a little differently from waterborne silt and mud, geologists acknowledge that the processes of depositing the materials are essentially the same.

This shows us that rhythmites that look like varves can be deposited all at once during catastrophic events. If conditions on Tree ring dating creation were ever more severe than they are today and they were, according to the Flood model of earth historythen we would expect to find many rhythmites in lakes. So counting the alternating fine and coarse laminae, like in varves, does not indicate years of deposition. Another example is Hurricane Donna, which flooded south Florida indepositing a 6-inch-thick mud layer with numerous thin laminae.

Tree ring dating creation June flood in Bijou Creek, Colorado, deposited a sediment layer with more than laminae in 12 hours. Recent sedimentation in Walensee, Switzerland, reveals that while an average of two laminae have developed per year, in some years rapidly flowing water has deposited as many as five layers on the bottom of the lake. Furthermore, scientists sometimes find vast, contradictory among their own dating methods. But they have run into trouble. Based on counting varves, they first estimated a chronology of 28, years for North America.

But the same data was reinterpreted as only about 10, years based on radiocarbon dating. Think about what this means. Counting varves is supposed to be more reliable than radiocarbon dates, which are usually corrected by varve and tree-ring counts!
