Many geologists claim that radiometric “clocks” show rocks to be millions of years old.However, to read any clock accurately we must know where the clock was set at the beginning.When they die no new carbon-14 is taken in by the dead organism.The carbon-14 it contained at the time of death decays over a long period of time.They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.
But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay.
So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.
