We cannot know with any certainty the age of most of the geological strata that is available to man for viewing.
I would still, however tentatively, tend to agree with a given, millions-of-years-old, Earth strata-age that enjoys near unanimous scientific support. Because I can't come up with a better scientific guess than they can, and it's their field, not mine.
Even carnivores that eat only animal tissue absorb C14 from that animal tissue.This, alone, should tell us something very important about today’s recognized scientific community.Nevertheless, there is such a thing as a real scientist, and real science is still being done. Note well that, when modern scientists speak of cosmic distances between celestial objects, and the velocities at which such objects are moving toward or away from us, they stand on much firmer empirical evidences for their statements than when they are speaking of the age of an ancient bone fragment or fossilized leaf.Aging anything on Earth in the hundreds of thousands of years, or in the millions or beyond, involves little more than educated conjecture. A Guess never rises above the level of being a guess, no matter how scientific, no matter how educated, no matter how much consensus it enjoys, no matter how well it "fits" any popular hypothesis.Even with full, 100% consensus in the scientific community, in the absence of any empirical evidence, conjecture still remains conjecture.
