(2) There's mostly left-handed amino acids (not yet decayed to a 50/50 right-to-left ratio) in chert and dinosaur eggshells.The pre-Flood world contained much more plant life (as seen in massive coal seams). Evidence from ancient pottery and lava flows indicate the magnetic field was stronger in the past.The stronger magnetic field would have shielded Earth from cosmic rays and solar flares resulting in less A fossilized ammonite and piece of wood in the Lower Cretaceous Budden Canyon Formation near Redding, California are assigned an age of 112 million to 120 million years old according to the geologic column.The radiocarbon method is often used as a starting point for understanding radiometric dating techniques, especially in classes unrelated to geology, because: 1) most are familiar with Carbon, as opposed to elements like Osmium, Neodymium, Rubidium, Thorium, etc.; 2) the technique is relatively easy to understand (try explaining a U-Pb concordia over dinner, if you don't believe me); and 3) the method is used in historical studies, such as the dating of artifacts or trees, which can be confirmed by more 'tangible' witnesses like tree ring counts (Sakurai et al., 2004).The third point is most relevant to our discussion, since it results in 'both sides' affirming the accuracy of radiocarbon dating for any 'recent' samples (as opposed to nearly any other method, which must be discounted in all cases by anyone that believes in a young Earth).
