The same mistake was made in the 1800s when an attempt was made to calculate the age of the Earth by simple cooling. The fossils occur in regular sequences time after time; radioactive decay happens, and repeated cross testing of radiometric dates confirms their validity. However, the discrepancy has turned out to be very real. Carbon-14 found in fossils at all layers of the geologic column, in coal and in diamonds, is evidence which confirms the biblical timescale of thousands of years and not billions.

Your argument does not follow. It depends upon radioactive decay, which is known to be extremely stable, not influenced my chemical processes, and which can be measured quite accurately.

The Age of the Earth - It is composed of little glass beads that come from volcanic ash.

Richardson, heological of geology at Iowa State University based on the glossary in Earth: An Introduction to Geologic Change, by S. Also a few entries from including Wesley R. Electron-capture decay The only type of radioactive decay that requires the presence of something daating an electron — outside the atom's nucleus. Electron capture decay of light atoms — geologicxl having the fewest electrons — accurcay be very slightly affected by extremely high pressures or certain chemical bonds, so as to change their half-lives by geological dating accuracy fraction of a percent. But no change in the half-lives of elements used for radiometric dating has ever been verified. Wiens Ice core Long sections of ice brought up by special drilling rigs on the ice sheets of Greenland and Antarctica Accurady />Wiens ; A sample of ice taken from glaciers or other accumulations, often showing seasonal layering. Most elements have more than one isotope. Most radioactive elements used for dating have one radioactive isotope and at least one stable isotope. For example carbon-14 which weighs 14 atomic mass units is radioactive, while the more common isotopes, carbon-12 and carbon-13 are not. Isotopes share the same. For example, oxygen atomic number 8 may have an atomic mass number of 16, 17, or 18, depending on whether it has 8, 9, or 10 neutrons. It therefore has three isotopes. Vendian The latest of the era, spanning the time between 650 and 544 geological dating accuracy years ago. Also referred to as the Ediacaran period, the Vendian is distinguished by fossils representing a characteristic collection of complex soft-bodied organisms found at several localities around the world. During the '90s Vendian replaced Ediacaran it seems the pendulum has now swung the other way, with Ediacaran is now the preferred term for this period. Xenolith Literally, a foreign chunk of rock within a rock. Some rocks contain pieces of older rocks within them. These pieces were ripped off the magma chamber in which the main rock formed and were incorporated into the rock without melting. Xenoliths do not occur in most rocks, and they are usually datinng by eye where they do occur. If unrecognized, they can result in an incorrect date for a rock the date may axcuracy of the older xenolith.
