Seeing as how this thread is already sidetracked into a mudhole, I'll ask a off topic question.
If all the elements on Earth were created at the same time as the material making up the Earth, how does radioactive isotope aging work? Weren't they all created at the same time and therefore the same age? If not, where is this new material being created?
Each element and isotope thereof decays as a different rate. It's not the overall age, but the state of decay and remaining half-lives of the elemental isotope.
