Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.
Mike Riddle exposes the unbiblical assumptions used in these calculations The primary dating method scientists use for determining the age of the earth is radioisotope dating.
Scientists calculate ages by measuring how much of the isotope remains in the substance.
Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.
In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).
In historical geology, the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young (radiocarbon dating with Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.
Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age.
For instance, if an object has 50 percent of its decay product, it has been through one half-life.
