Radiometric dating age of the earth
Other creationists hold that the planet itself was created during creation week, perhaps early in the first day of creation.
In this case, the entire planet would be about 6,000 to 10,000 years old.
So, we have a “clock” which starts ticking the moment something dies.
Obviously, this works only for things which were once living.
Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.Radiometric dating is a method which scientists use to determine the age of various specimens, mainly inorganic matter (rocks, etc.), though there is one radiometric dating technique, radiocarbon dating, which is used to date organic specimens. Basically, scientists take advantage of a natural process by which unstable radioactive “parent” isotopes decay into stable “daughter” isotopes spontaneously over time.Uranium-238 (U238), for example, is an unstable radioactive isotope which decays into Lead-206 (Pb206) naturally over time (it goes through 13 unstable intermediate stages before it finally stabilizes into Pb206).The minerals of the earth often contain atoms that are unstable and decay into a different kind of atom. The rate of radioactive decay can be described by a mathematical equation that compares the ratio of “parent” radioactive atoms to “daughter” atoms resulting from radioactive decay.Using this equation, scientists can calculate how long it would take for radioactive decay to produce the observed ratio of parent and daughter material. Several different types of radioactive atoms are used to calculate radiometric dates, such as uranium-lead, rubidium-strontium, etc.
