Why does uranium and carbon dating not come up with numbers like the one 
in the "Question" field? They measure how much of an element decomposed 
since the fossil formed, but what about before that? The carbon you 
extracted from a 5000-year-old wild horse or uranium from a millionarian 
(is that a word? Centenarian is) piece of rock existed and decomposed 
before they became a horse and a rock. So, why is that not reflected?
