Creationists now feel that billions of years worth of radioactive decay has occurred on earth, giving old isotopic dates, but this decay took place in only a few thousand years.
The question is why isotopic
dates give such old ages.In the past
Creationists often said it was because the system was disturbed.
There may have been daughter
substance present initially or parent substance may have been removed, for
example.However geologists have been
careful to account for such possibilities.Now creationists tend to believe the explanation is different.
