I thoroughly researced the methodology used to establish Earth age by the current standard of analysis of uranium decay.
I acknowlege that there are other methods of dating, using different physical properties of different substances, that are of differening accuracy, within differing time ranges.
Now I've acknowleged the existence of these other clocks, but my doing so has not changed the decay rates of uranium and it's daughter elements. To what end is that acknowlegement to be used?
Well you could state all of the assumptions applied - for instance the ratio of father to daughter elements when a clock is reset. You might also acknowledge since there are no instruments that can withstand these temperatures you have no certitude regarding uniform decay rates for all temperature extremes. Maybe you could also indicate that for all the known layers of strata there is no where on Earth where all ten major epoch layers are represented.
Heck you might even check the link I gave you or the other young natural clocks I cited instead of thinking strictly in radiometric clocks.
Nah forget it - you are much too certain of your methods to allow for any uncertainty. Afterall evolution has been declared a proven scientific theory so why waste anymore time.
