Mishandled Data Determine New Hominid Ages
A recent report in the journal Science mixed detailed archaeological finds with stories about human origins. As is typical, age assignments for fossils fit evolutionary time instead of the Bible’s much shorter timeline of thousands, not millions, of years. But the age-dating exercises revealed more about what these scientists believe about the past than what the rocks and fossils themselves reveal.

A cave on the Portugal coast has Neanderthal human remains. A University of Göttingen press release says that archaeologists found these ancient cave-living humans ate “mussels, crustaceans and fish as well as waterfowl and marine mammals such as dolphins and seals.”1 Neanderthals went fishing?

Say goodbye to old images of Neanderthals as primitive hunter-gatherers. The Science report also noted that the site showed that “the pattern of tortoise shell burning is consistent with the roasting-in-carapace technique.”2 This new evidence reaffirms that Neanderthal peoples were people like me and you. But when did they inhabit this and other caves in southern Europe?

The Science report dates these Neanderthal remains “to ~86 to 106 thousand years ago.”2 Of course that exceeds the biblical age of the world. What actual evidence demands that the Bible got its history wrong?

The process of age dating can begin by assigning rocks or fossils to predetermined age designations like those named MIS (Marine Isotope Stage). These supposed stages derive from interpretations of isotope differences found in seafloor sediments. Isotope ratios vary with core depth, but when did each variation happen? Evolutionists used astronomical cycles that assume old ages in the first place to pin long ages onto the isotope shifts. That’s circular reasoning, not good science.

Dr. Jake Hebert meticulously traced the origins of the sediment core age assignments that produced names like MIS 3. He quoted from the experts who constructed these evolutionary charts over the last half century who admitted ways to contrive apparent agreement between natural clock-like processes and evolutionary time expectations. Hebert’s detailed and fascinating results appear in technical online reports like this one, which has not yet suffered refutation since its publication six years ago.3

But the archaeologists working on Neanderthal remains probably have no clue or concern that their timeline-building colleagues massaged isotope and other data to force it into long age models. Accordingly, this archaeology team wrote, “This site has been assigned to MIS 3 or MIS 4 on the basis of anchoring OSL dating results to radiocarbon chronologies, though the latter must be minimum ages only.”2 “OSL” refers to optically stimulated luminescence. If OSL actually worked as a dating method, then nobody would need to anchor it to an outside chronology. And if radiocarbon chronologies were real, then workers would take them at face value instead of sidelining them as “minimum ages only.”

Similarly subjective handling of supposedly absolute age indicators came buried in the whopping 171 page Supplemental Materials that accompanied this Science study. The first line in the University of Göttingen Press Release says, “Over 80,000 years ago Neanderthals were already feeding themselves on…fish.”1 So what did the study authors do with a radiocarbon result for one of the cave’s limpet shells of 2,677±28 BP?4

The team conveniently claimed that this and other shells were younger, but got “reworked” into older layers.5 Logically, if they can claim these samples entered much older sediments, then how do they know that any or all of their other samples came from other times? To dismiss age results that do not match expectations is to allow beliefs, not data, steer conclusions.

Some of their radiocarbon ages not only disagreed with one another and with evolutionary time expectations, but they disagreed with a different technique, too. The team used uranium-series dating to assign ages to the tiny mineral layers in cave structures like stalactites. The study authors wrote, “However, the radiocarbon ages obtained for them [shells] are significantly younger than the speleothems sealing the deposit they were found in.” Oops.

As one more example among many in this report’s collection of wonky age results, the team lined up radiocarbon ages from a series of artifacts in top-to-bottom order. They came in exactly the wrong relative age order! The study authors wrote, “In addition, the complete set of Entrance 3 radiocarbon dating results features a fully reversed relationship between age and stratigraphic depth.”6 Oops again.

The study authors invoked bacterial activity, precipitation of carbonates, and isotope exchange as processes that may have altered the carbon isotope ratios enough to make some of them give wrong ages. But how do they know one or all three of these factors did not ruin all the radiocarbon ages? At each of these points of discord, workers selected an “age” that aligned with their beliefs, which include human evolution over eons. Responsible science rejects the whole lot as meaningless numbers.

Deeply buried beneath boldly stated claims like “over 80,000 years ago,” an underground ant bed of workers scrambles to scrub their results until they confirm deep-time beliefs. In reality, these discordant, reverse-ordered, and subjectively dismissed or approved “ages” pose no more threat to the Bible’s eyewitness history than do any given numbers of Monopoly money dollars in a child’s hand.
