These new rocks rapidly accumulated more Pb isotopes due to the concurrent accelerated radioactive decay of U and Th in them during the Flood.Thus, without being able to unequivocally distinguish the daughter Pb atoms produced by in situ U and Th decay from the initial Pb atoms in a mineral or rock, it is impossible to determine their absolute U-Pb ages.The absolute ages provided by the radioisotope dating methods provide an apparent aura of certainty to the claimed millions and billions of years for formation of the earth’s rocks.Many in both the scientific community and the general public around the world thus remain convinced of the earth’s claimed great antiquity.Once radioactive decay of U and Th started after creation, daughter Pb isotopes were added inside the earth.Then catastrophic plate tectonics during the Flood stirred the mantle and via partial melting added new rocks to the crust.One crucial area the RATE project did not touch on was the issue of how reliable are the determinations of the radioisotope decay rates, which are so crucial for calibrating these dating “clocks.” However, in a recent series of papers, Snelling (2014a, b, 2015a, b, 2016, 2017) reviewed how the half-lives of the parent radioisotopes used in long-age geological dating have been determined and collated all the determinations of them reported in the literature to discuss the accuracy of their currently accepted values.

Among them is the presence of non-radiogenic Pb of unknown composition, often referred to as common or initial Pb.

He showed that there is still some uncertainty in what the values for these measures of the Rb decay rate differ when Rb-Sr ages are calibrated against the U-Pb ages of either the same terrestrial minerals and rocks or the same meteorites and lunar rocks.

Ironically it is the slow decay rates of isotopes such as Sm used for deep time dating that makes precise measurements of their decay rates so difficult.

All the unprovable assumptions ultimately depend on an assumed deep time history.

Its rejection is recognized as fatal to the earth’s claimed age of billions of years.
