How radiometric dating works in general radioactive elements decay gradually into other elements the original element is called the parent and the result of the decay.
Different samples of the same isotope all have the same halflife the halflife of a particular isotope is always the same it doesnt depend on the size of the sample and it doesnt change with time.
before present bp years is a time scale used mainly in geology and other scientific disciplines to specify when events occurred in the past because the present time changes standard practice is to use 1 january 1950 as the commencement date of the age scale reflecting the origin of practical radiocarbon dating in the 1950s the abbreviation bp has alternatively been interpreted as.
dating principles of isotopic dating all absolute isotopic ages are based on radioactive decay a process whereby a specific atom or isotope is converted into another specific atom or isotope at a constant and known rate most elements exist in different atomic forms that are identical in their chemical properties but differ in the number of neutral particlesie neutronsin the nucleus.

Overview the theory of evolution describes an earth that is about 45 billion years old but many creation scientists interpret the genesis account of creation as requiring an earth that is only 6000 to 10000 years of agethere are numerous indicators that the earth was in existence billions of years ago.
