The oldest known wooden tools have been found in an opencast mine in Greece. They are 430,000 years old and were made by an unidentified species of ancient human – perhaps the ancestors of Neanderthals.

But the Neanderthals were the descendants of Adam and Eve, there is something wrong about the date of 430 000 years.

Prehistoric wooden artefacts are “very scarce”, says archaeologist Dirk Leder at the Lower Saxony State Office for Cultural Heritage in Hannover, Germany, who wasn’t involved in the study. “Every single find is welcome.”

WWII Bomber Plane P-38 Found 300 Feet Below the Ice in Greenland

A World War II airplane that was lost in Greenland has been spotted by an aerial drone.

On July 4, 2018 California businessman Jim Salazar told the wrecked P-38 was beneath “more than 300 feet (91 meters) of ice using a ground-penetrating radar antenna fitted to a heavy-lift aerial drone.”

“This latest find echoes the 1992 recovery of another P-38 fighter from the same ‘Lost Squadron’ of U.S. warplanes in Greenland. That fighter was eventually restored to flying condition under the name ‘Glacier Girl’.

Both aircraft were part of a group of two B-17 bombers and six P-38 fighters flying from the U.S. to Britain in July 1942. They were traveling through a chain of secret airbases in Newfoundland, Greenland and Iceland known as the Snowball Route.

Hundreds of U.S. aircraft flew this route during World War II as part of Operation Bolero, which delivered warplanes, pilots, equipment and supplies for the planned Allied invasion of Nazi-occupied Europe.”

This brings to nought the geological sediments, which are thought to be millions of years old.

A new surview has just announced that the James Webb Space Telescope  “has spotted five galaxy candidates dating to just 200 million years after the Big Bang”.

According to evolutionists, the “13.6 billion light-years away and just 200 million years after the Big Bang, are five galaxy candidates are the earliest ever detected”.

There is a problem with dating methods, since according to evolution, space events  are always counted in millions of years.

 ”Crystals inside a Martian meteorite hint that there may have been plentiful hot water on Mars when the rock formed "4.45 billion years" ago.

The rock, nicknamed Black Beauty, was blasted into space by an impact on the surface of Mars before ultimately crashing into the Sahara Desert Morocco in 2011 and is formally known as Northwest Africa 7034.

Aaron Cavosie at Curtin University in Perth, Australia, and his colleagues have spent years studying a tiny fragment of it that includes a zircon crystal measuring 50 micrometres across.

Cavosie describes Black Beauty as a “garbage can” rock because it was formed from hundreds of fragments smashed together. “It’s a wonderful buffet of Martian history, a mixture of very old and very young rocks,” he says. “But many of the fragments in it are among the oldest pieces of rock from Mars.”

The evolutionists believe that the solar system was formed 4,5 billion years ago, but the dating methods are full of danger.

A saber-tooted cat was found in Siberia.  Evolution believing scientist say that the cat is at least 35,000 years old. But what is fascinated in the find  the kitten still has its whiskers and claws attached.

According to evolutionists, ”saber-toothed cats of the extinct genus Homotherium lived across the globe during the Pliocene (5.3 million to 2.6 million years ago),” but many scientists, as they say that dating methods give a false sense of the earth’s age.

“Around 7000 years ago, long knives, bracelets and other stone goods fashioned by skilled Parisian crafters were reaching people hundreds of kilometres away, via complex trade networks that are now being mapped for the first time.

By combining archaeology with computer modelling, Solène Denis at the French National Centre for Scientific Research in Nanterre and Michael Kempf at the University of Basel in Switzerland have reconstructed the lengthy and winding paths taken to supply people from what is now Normandy.”

This study does not take the effects of the Genesis Flood into consideration that occurred about 4500 years ago so there is a different in dating methods.

Living microbes found deep inside ”2 -billion-year-old” rock

Millions of years and evolution seem to go together,  yet research says that here are faults in dating methods is significant that the Darwinist will be silent on.

For them, millions of years is almost  secret, that cannot be disproved.

New Stcitentis says:

“Microorganisms have been found living in tiny cracks within a 2-billion-year-old rock in South Africa, making this the oldest known rock to host life. The discovery could offer new insights into the origins of life on Earth and may even guide the search for life beyond our planet.

We already knew that deep within Earth’s crust, far removed from sunlight, oxygen and food sources, billions of resilient micro-organisms survive. Living in extreme isolation, these slow-growing microbes divide at a glacial pace, sometimes taking thousands or even millions of years to complete cell division.

“So far, the oldest rocks in which microbes have been found are 100-million-year-old seafloor sediments,” says Yohey Suzuki at the University of Tokyo. “We know it’s possible that microbes can grow using something in these ancient rocks.”

Now, Suzuki and his colleagues have pushed that record back by nearly 2 billion years. They obtained a 30-centimetre-long cylindrical rock core from 15 metres below the surface of the Bushveld Igneous Complex in north-eastern South Africa, a vast formation of volcanic rock that formed more than 2 billion years ago. When they sliced open the core, they discovered microbial cells living in the rock’s tiny fractures.”

Radiocarbon Dating Might Give Too Old Dates, at Least in the Levant

Image: Julius Schnorr von Carolsfeld (1794-1872), The Battle of Jericho, Public Domain.




Joel Kontinen

Radiocarbon dating is thought to be a highly reliable dating method, but a new paper published in the journal PNAS suggests that carbon dates may be off by several decades and, in some cases, a hundred years or so.

Other dating methods are even less reliable.

Manning et al. state:

“We observe a substantive and fluctuating offset in measured radiocarbon ages between plant material growing in the southern Levant versus the standard Northern Hemisphere radiocarbon calibration dataset derived from trees growing in central and northern Europe and North America. This likely relates to differences in growing seasons with a climate imprint.”

They go on to say:

“This finding is significant for, and affects, any radiocarbon application in the southern Levant region and especially for high-resolution archaeological dating—the focus of much recent work and scholarly debate, especially surrounding the timeframe of the earlier Iron Age (earlier Biblical period). Our findings change the basis of this debate; our data point to lower (more recent) ages by variously a few years to several decades.”

The half-life of Carbon-14 is 5,730 years, so the study does not affect really old dates.

Evolutionists will not carbon date dinosaur bone, though they certainly should do so, as they’re known to contain C-14, thus falsifying the dogma of millions of years.

And they should date coal and diamonds as well.

Lightning Can Produce Atmospheric Radiocarbon (C-14)

More radiocarbon forming? Image courtesy of Simon Q, CC BY 2.0.




Joel Kontinen

In February a thunderstorm in Japan had unexpected consequences. Teruari Enoto, an astrophysicist at Kyoto University, and his colleagues discovered that lightning produced more atmospheric radiocarbon.

A news article in Nature states:

“The main source of the carbon-14 in the atmosphere has generally been considered to be cosmic rays. In principle, lightning could also contribute to the supply. But it is not clear yet how much of the isotope is produced in this way, says Enoto, in part because it’s possible that not all bolts initiate photonuclear reactions.”

Many evolutionists used to think that radiometric dating methods were reliable, but a number of studies have shown that they were wrong.

This applies to several dating methods and their basic assumptions.

Geologists will now admit that zircon crystals, ultrasonic cavitation and even solar flares can skew dates.

In addition, science publications have suggested that the uranium-lead method and some other methods tend to give too old dates.

Radiocarbon dating is a special case, as it does not give dates in the millions of years due to its relative short half-life of approximately 5,730 years.

Nonetheless, the Japanese study suggests we should be a bit more critical of radiocarbon dates as well.

New Research Spots a Key Flaw in Radioisotope Dating Methods

Younger that previously assumed? Image courtesy of Meteorite Recon, Creative Commons (CC BY-SA 3.0).




Joel Kontinen

New research published in the journal Nuclear Technology challenges a basic assumption of radiometric dating. Science Daily gives a brief overview of the problem:

“An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples.”

The article describes the issues involved in rubidium-strontium dating. Rubidium-87 decays to Strontium-87 over time, so the amounts of isotopes in a rock sample or other objects should make it possible for scientists to calculate the age of the sample.

This should be more or less straight-forward. In theory, it is. But in practice, it’s a bit more complicated:

“The data from radioisotope analysis tends to be somewhat scattered. So, researchers ‘normalize’ the data by making a ratio with strontium-86, which is stable -- meaning it doesn't decay over time.

Dividing the isotope concentrations of all the forms of strontium and rubidium by the isotope concentration of strontium-86 generates something called the "isochron." The isochron is then plugged into a model, which uses it to turn the overall radioisotope data into a clear, linear function. This function is able to tell researchers how old a sample is. Or it's supposed to.
But there's a wrinkle in the process that has been overlooked.

The ratios of strontium-86 to rubidium and strontium-87 are thought to only be influenced by the radioactive decay of the rubidium-87 into strontium-87. The current model of radioisotope dating is based on that idea.

But that model doesn't account for differential mass diffusion -- the tendency of different atoms to diffuse though a material at different rates. And atoms of strontium-86 can diffuse more readily than atoms of strontium-87 or rubidium, simply because atoms of strontium-86 are smaller.
”

Associate Professor Robert Hayes, the author of the paper, says that different types of rocks will give differing results and things like “the number of cracks and amount of surface area” will also have an effect on the rate of diffusion, and hence the assumed age.

This is not the first time that researchers doubt the accuracy of radiometric methods. Several other papers have likewise cast doubt on the reliability of dating techniques. See details here, here, here and here.

Science: Radiometric Dating Methods Give Too Old Dates


These rocks are not as old as was assumed, new research suggests.






Joel Kontinen


Radiometric dating methods have problems that cannot be characterised as minor. Last week Science published two reports that have a bearing on the age of rock layers.

The problems have to do with the half-lives or the time in which certain atoms decay or turn into other atoms.

According to the first study, the half-life of Samarium-146 is approximately 30 per cent shorter than previously assumed. The previous figure of 103 ± 5 million years has to be discarded. The new figure is about 68.7 million years.

The second paper indicates that the ratio of Uranium-238 to Uranium-235 was not the same in all rocks (137.88:1) but that it varies from 137.743:1 to 138.490:1.

Commenting on the importance of the study for Nature news, Daniel Condon of the British Geological Survey, whose team conducted the research, says that many rocks are roughly 800,000 years younger than previously assumed.

This means that in practice, everything else, including meteorites and moonstones, are younger than assumed. Thus even fossils found in rock layers should be somewhat younger than what textbooks state.

For two centuries, the idea of millions of years has been respected as a dogma that cannot be criticised.

Science publications have occasionally reported on discrepancies in dating methods. Read more here and here.

Cave Expert Dr. Emil Silvestru Talks About Caves, Noah’s Flood and Radiometric Dating

Joel Kontinen

Emil Silvestru of Creation Ministries International – Canada is a karstologist or cave expert with a PhD in geology. In the following video clips he is interviewed by Jim Cantelon of 100 Huntley Street. He talks about caves, Noah’s flood and radiometric dating methods.

Dr. Silvestru says that science in not about the facts but about how one interprets the facts.

There is much that speaks for a global flood, such as the existence of enormous flat erosion surfaces (planation surfaces) in mountains covering huge areas, even 1 million square kilometres, the continuity of sediments (the Cococcino Sandstone, for instance, covers half a million square kilometres in North America), and massive layers of dead animals all over the world.

Dating methods are always based on assumptions, which are based on more assumptions. Dr. Silvestru mentions that carbon-14 has been found in diamonds that are assumed to be as old as 3 billion years. In 1970, an exceptionally well-preserved muskox fossil found in the Yukon Territory was C-14 dated. The muscles at the back of the head gave a date of 24, 000 years and the fur 17,000 years. He has an interesting explanation for this discrepancy.

Young Graphite in Old Rocks?



The age difference between the oldest and youngest estimated date of these rocks is 1.75 million years.



Joel Kontinen

”Young Graphite in Old Rocks” sounds like a headline in Creation magazine, but this time it is from ScienceDaily, a site known for its unwavering pro-Darwinian approach.

Dominic Papineau, an associate professor at Boston College, and colleagues recently published a paper in Nature Geoscience on the ancient rocks in the Hudson Bay area in Canada.

The researchers think that the graphite in the rocks is several millions of years younger than the rocks. (Graphite is one of the allotrophic forms of carbon.)

The rock itself is assumed to be 3.8 – 4.2 billion years old. It seems that finding carbon in so old rock is not compatible with evolutionary thinking, so the researchers have to assume that the graphite must have entered the rocks later.

All known life on Earth is carbon-based. The evolution model does not allow for life to be born too early, so the ancient carbon creates a huge problem and a need for finding explanations.

Carbon is an interesting substance since diamonds for instance are a form of carbon. They actually contain C-14 that has a half life of 5, 730 years. This means in effect that diamonds said to be billions of years old cannot be older than some tens of thousands of years.

It real life, the dog wags its tail. In some ideologies, the tail obviously wags the dog.

When algae forgot to evolve – for a billion years



Somewhat younger algae. Image courtesy of Eric Guinther, Wikipedia.



Joel Kontinen


Researchers assume they have found new living fossils. The algae living at a depth of over 200 metres (650 feet) in the waters of New Zealand belong to the genera Palmophyllum and Verdigellas.

Recently, professor Frederick Zechman of California State University at Fresno and colleagues published a study on the genetic makeup of these algae in the Journal of Phycology. The researchers concluded on the basis of the algae’s DNA that they are closely related to algae they assume are a billion years old.

Although there are no fossils of so old algae, professor Zechman suggests that they are living fossils.

Evolution is often defined as change over time but it seems to have forgotten to change many species. For instance, the Coelacanth (Latimeria chalumnae), squids, octopuses, tuataras, horseshoe crabs and dragonflies have resisted Darwinian change for aeons.

Stone age Papuans were not primitive



Ancient people were not primitive. For instance, the stone age people in Gran Canaria, Spain, made elaborate clay vases.




Joel Kontinen

The more archaeologists discover about the customs and cultures of ancient man, the more obvious it becomes that the findings do not correspond to the Darwinian concept of ape-like early men.

Recently, Glenn Summerhayes, an archaeologists at the University of Otago, New Zealand, and colleagues published a paper in Science on the ancient inhabitants of Papua New Guinea. They assume that the inhabitants of Ivane Valley, an area 2, 000 metres above sea level that is surrounded by high mountains, tilled the ground 49,000 years ago.

Summerhayes and his colleagues discovered ancient Papuan campsites that had been covered by volcanic ash. Professor Summerhayes assumes that the people hunted small animals, cleared plots in the forests and collected nuts. He also thinks that the Papuans brought yams into the mountains from the lowlands.

The research team also found stone tools in the area.

Although evolutionists almost always overestimate the age of ancient discoveries, these findings agree well with that what Genesis tells about early men. They had a relatively high culture almost at the dawn of human history. Cain already built a town and soon Adam’s descendants made musical instruments and bronze and iron tools.

The view that ancient man was primitive is a myth that lacks evidence.

Amazing discovery: Solar flares have an effect on radioactive decay



Solar flares can have an effect on radioactive decay. Image courtesy of NASA.




Joel Kontinen

Researchers usually assume that radioactive elements decay at a constant rate although some studies conducted in the past few years (read more here and here) throw a dark cloud over this view.

Last week Stanford University published an intriguing report on the effect of solar flares on the decay of radioactive elements. This new research challenges ingrained beliefs in the reliability of dating methods.

It all began at Purdue University, where a group of researchers was trying to use the decay rate of radioactive isotopes to generate random numbers. They soon found out that the decay rates were not as regular as they had assumed and that there were irregularities in research conducted in the field.

Then they discovered that silicon-32 and radium-226 decay slightly faster in winter than in summer. Peter Sturrock, emeritus professor of applied physics at Stanford University, says: "Everyone thought it must be due to experimental mistakes, because we're all brought up to believe that decay rates are constant."

In December 2006 Jere Jenkins, a nuclear engineer at Purdue University, measured the decay rate of manganese-54 and found out that it dropped slightly about a day and a half before a solar flare.

Jenkins and Ephraim Fischbach, who studies random numbers at Purdue University, concluded that the Sun’s neutrinos have an effect on the decay rate.

Peter Sturrock, who studies ”the inner workings of the sun”, advised them to check previous research results on how the Sun’s rotation had an effect on the decay rate of radioactive elements measured on Earth. They found a clear 33-day cycle.

In other words: isotopes do not decay at a constant rate.

The discoveries at Purdue and Stanford could revolutionise our thinking about dating methods. Faith in millions of years might well weaken once people realise the significance and implications of the research results.

However, the ideological baggage associated with the idea of millions of years might cause some skeptics to reject the new discoveries like they initially refused to believe in the discovery of soft tissue in dinosaurs and carbon-14 in diamonds.

Science: The uranium-lead dating method gives too old dates



Perhaps these rocks in southern Finland are much younger than was supposed.




Joel Kontinen

For the most part, scientists have assumed that radiometric dating methods give reliable results. They have thought that nothing else except radioactive decay has had an effect on the amount of parent isotopes (the original radioactive substances) and daughter isotopes (the decay products) in rocks.

A new paper published in Science challenges this view. Gregory Brennecka, a geochemist at Arizona State University, and colleagues studied meteorites by using mass spectrometry and found out that their original 238U/ 235U ratio was not stable but varied.

The uranium-lead method is based on the knowledge that uranium-238 decays into lead-206 and uranium-235 into lead-207.

The researchers conclude that results obtained by this method are roughly five million years too old. In other words, our solar system is much younger than previously supposed.

This is not the first paper to throw doubts on the assumptions behind radiometric dating. Last July, CERN, The European Organization for Nuclear Research, published a study that showed that ultrasonic cavitation in water caused thorium-228 to decay 10, 000 times faster than previously supposed.

It thus seems that the model based on Genesis is becoming increasingly relevant.

Squid Ink Assumed to be 150 Million Years Old Challenges Belief in Millions of Years



Newly found squid ink suggests that the assumed millions of years never existed. Image of a modern-day squid courtesy of Hans Hillewaert, Wikipedia.





Joel Kontinen

Palaeontologists have found fossilized squid ink in England. The one-inch (2.5 cm) long black ink sac of a fossil assumed to be 150 million years old was well preserved.

The ink is as good as new. The researchers used it to draw a picture of the squid. They also used the ink to write the squid's Latin name Belemnotheutis antiquus.

Dr. Phil Wilby of the British Geological Survey said that the animal closely resembles modern squids. He suggests its preservation is an enigma. ”It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilized in three dimension, still black, and inside a rock that is 150 million years old,” he said.

According to the researchers, the probability of finding a fossilized ink sac is one in a billion. The new discovery joins dinosaur soft tissue and C-14 found in diamonds to challenge belief in millions of years.

The squid fossil shows signs of rapid burial, suggesting it met its end in a catastrophe such as Noah’s Flood. In addition, it shows no signs of evolution.

New research raises doubt on assumptions behind radiometric dating


What if these rocks in southern Finland are 10 000 times younger than supposed?




Joel Kontinen


CERN, The European Organization for Nuclear Research, recently published an interesting report on the radioactive decay of thorium-228. The research throws doubt on the view that external conditions cannot have an effect on decay rates.

The new study reveals that the “closed-system, no contamination” assumption is not correct. Fabio Cardone of the Institute per lo Studio dei Materiali Nanostrutturati in Rome and his colleagues noticed that ultrasonic cavitation in water caused thorium-228 to decay 10, 000 times faster than previously supposed.

The effect of water raises interesting questions. Do other radioactive substances also decay at faster rates than previously assumed? There is plenty of water on Earth and the global flood in Noah’s days is beginning to be an even more plausible explanation for accelerated decay rates.

The CERN report also states that scientists had previously noticed minor deviations from expected decay rates.

Popular science magazines have presented radioactive decay rates as almost absolute although geology abounds with “bad dates”. The new study suggests that we should take a skeptical approach to the belief in millions of years of earth history.
