Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology.It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).But for humans whose life span rarely reaches more than 100 years, how can we be so sure of that ancient date? Even the Greeks and Romans realized that layers of sediment in rock signified old age.But it wasn't until the late 1700s -- when Scottish geologist James Hutton, who observed sediments building up on the landscape, set out to show that rocks were time clocks -- that serious scientific interest in geological age began.

As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages.Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
