Let’s analyze their chain of arguments very carefully. They examined tiny zircon grains, each measuring about the width of four human hairs.As we unravel their claims, the discerning reader will see that the whole tapestry Valley has woven falls apart. These zircons were extracted from a metamorphosed sandstone layer in a low range of hills called the Jack Hills on a sheep ranch in a remote arid region about 500 miles (800 km) north of Perth, Western Australia. From here on Valley’s team makes assumptions to build each level of their interpretation.Because secular scientists like Valley believe the earth is 4.56 billion years old, they believe this little crystal has a lot to say about the earth shortly after it coalesced into molten rock from matter thrown from a solar nebula.Oxygen isotope ratios in the crystal are consistent with formation in an environment that contained liquid water.And what kind of rock could have produced these zircons in the first place?Since zircon grains initially crystallize at high temperatures (1800°C), the team assumed the zircon grains in this sandstone must have come from a rock crystallized from hot magma.Image: John Valley et al./University of Wisconsin-Madison in Nature Geoscience through This is a timeline purporting to display the unwitnessed version of earth’s history created by those who disregard God’s eyewitness account of our origins.It is not possible to accept this version of history, which is built on a host of unverifiable assumptions piled one upon another, without disregarding God’s Word and implying that He is a liar.

First, it is assumed that the particles making up the Jack Hills sandstone in which the zircons were found were eroded from pre-existing rocks and transported by water to be deposited in this layer.Oxygen isotopes and atoms of radioactive uranium trapped in the crystals are, many believe, frozen in time.Confined as they are in these crystals, many scientists believe that the ratio of parent radioactive uranium to daughter lead atoms in zircons can be used to calculate the ages of the crystals.Though apparently impervious to their environmental conditions, zircons can be ravaged from within.

Radiation emitted from trapped uranium and thorium atoms can disrupt their crystalline structure.

From it they suggest information the secular world finds surprising about hospitable conditions on the early earth.
