Dogmatic speculations in the form of radiometric dating I've always been able to handwave as untenable.
Sampling error, epoch isotopic concentrations, and blatent guessing are just a few tarnishing factors that make such time-pieces untrustworthy.
Moreover, they presuppose constancy in the speed of light over eons of time, and, not to mention, that higher elements on earth were somehow formed after the initial creation (AKA Big-Bang).
Anyone out there want to dogmatically speculate that higher elements and their isotopes were really somehow captured by our solar system, e.g., after a miraculously nearby super-nova produced them?
Or did our sun itself somehow produce the higher elements us radiometric daters confide in.
I for one find it very much easier to believe earth's higher inorganic elements and their radiometric isotopes (if you will) were formed at or very nearly at the beginning of the creation.
Now if all were formed in the beginning and stretched accross the universe at nearly the speed of c, then a whole bag of boggling relativistic scenarios could constrict atomically calibrated time within orbital clocks.
In other words, the number of earth's evenings and mornings would be far fewer compared to radiometric derivations of the same.
Albeit, the YEC's presupposition that God created mature chemistries would seem valid only assumming the Creator wished to make them appear cursed like us (e.g., to decay and die).
Then other metaphysics, like redemptive phenomena, restorative events, and God-of-the-gaps realities, must be entertained, not just due to our perverse lack of a scientific grasp of light and time, but due to our gross need to better qualify time as a metaphysical entity.
Just because we materialists accurately apply time in math and science doesn't make it a mere scientific phenomenon. Time is an elusive entity, like light, and demands an awesome appreciation beyond the material laws it associates with.
Conceptual time, for example, defies scientific constraints. Our scientific use of time is dwarfed by our racing with time in life's real painful events.
Thus, radiometric dating doesn't work for me either; other clocks, like geological and orbital clocks, must take precedence.
