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. Let’s give a little history of where these two basic calculations came from and which worldview is more reasonable. Of course, the Bible doesn’t say explicitly anywhere, “The earth is 6,000 years old.” Good thing it doesn’t; otherwise it would be out of date the following year.But we wouldn’t expect an all-knowing God to make that kind of a mistake. In essence, He gave us a “birth certificate.” For example, using a personal birth certificate, a person can calculate how old he is at any point. Genesis 1 says that the earth was created on the first day of creation ().Connected to internal radiation damage, these processes partially disrupt the crystal structure and partly explain the highly variable properties of zircon.As zircon becomes more and more modified by internal radiation damage, the density decreases, the crystal structure is compromised, and the color changes.From there, we can begin to calculate the age of the earth.Let’s do a rough calculation to show how this works.Zircon is also very resistant to heat and corrosion.Because of their uranium and thorium content, some zircons undergo metamictization.
The name derives from the Persian zargun meaning gold-hued. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.
There are two reasons uncalibrated dates must be mentioned: 1) this prevents people from making up any number they please, and 2) it is for the sake of posterity, where future scientists can check the results and apply new ideas of calibration. Radiocarbon dates are affected by many outside factors.
The accuracy of the machines is not in question (especially modern ones, which are astoundingly accurate when properly zeroed in). But, any source of old carbon in the ancient environment can affect the amount of C-14 in a sample.
These cosmogonies were part of the new emphasis of science in seeking rational explanations of the features of the world. This period was marked by a great deal of field geology rather than grand cosmogonies.
It became clear that there had been significant changes in the Earth's topography over time and that these changes could neither be accounted for by natural processes operating during the brief nor by the postulated Noachian flood.
