“Conclusions “After six decades of numerous careful radioisotope dating investigations of these achondrite meteorites their Pb-Pb, U-Pb, and Pb-Pb-calibrated isochron and model age of 4.55–4.57 Ga has been well established. This date for these achondrites is supported for most of them by a strong clustering of their Pb-Pb, U-Pb, and Pb-Pb-calibrated isochron and model ages in the 4.55–4.57 Ga range, as well as sometimes being confirmed by both isochron and model age results via the K-Ar, Ar-Ar, Rb-Sr, Lu-Hf, Re-Os, and Sm-Nd methods. The Hf-W, Mn-Cr, Al-Mg, and I-Xe methods are all calibrated against the Pb-Pb method, so their results are not objectively independent. Thus the Pb-Pb dating method stands supreme in the conventional evolutionary uniformitarian community as the ultimate, most precise tool for determining the ages of these achondrite and other meteorites. “There are no discernible patterns in the isochron and model ages for these achondrites, apart from scattering of many K-Ar, Ar-Ar, Rb-Sr, Re-Os, and Sm-Nd isochron ages and a few Pb-Pb and U-Pb isochron ages, and the considerable scattering of many K-Ar, Ar-Ar, and Rb-Sr model ages and some Pb-Pb, U-Pb, and Th-Pb model ages. The radioisotope ages for these achondrites do not follow the systematic pattern found in Precambrian rock units during the RATE project. The α-decay isochron ages are not always older than the β-decay isochron ages for particular achondrites, and among the β-decayers the isochron ages are not always older according to the increasing heaviness of the atomic weights of the parent radioisotopes, or the increasing lengths of their half-lives. Thus there appears to be no consistent evidence in these achondrite meteorites similar to that found in earth rocks of past accelerated radioisotope decay. Therefore it could be concluded from these data that no accelerated radioisotope decay event has occurred on the asteroids which parented these achondrite meteorites. “Any explanation for the 4.55–4.57 Ga age for these achondrite meteorites needs to consider their origin. These meteorites are regarded as fragments of asteroids, debris derived from impact cratering of their surfaces and collisions with other asteroids. Even in the naturalistic paradigm the asteroids, and thus the meteorites, are regarded as “primordial material” left over from the formation of the solar system. Similarly, it has been suggested the Hebrew of the Genesis text allows for God to have made “primordial material” on Day One of the Creation Week from which He made the earth on Day One and the non-earth portion of the solar system on Day Four. Thus today’s measured radioisotope compositions of these achondrites may reflect a geochemical signature of that “primordial material,” which included atoms of all elemental isotopes created by God. “Therefore if some, or perhaps most, of the daughter isotopes measured today in these achondrite meteorites were thus “inherited” by them when they were formed from that “primordial material,” and the parent isotopes in these meteorites have only been subjected to some subsequent radioisotope decay (and none at accelerated rates), then the 4.55–4.57 Ga Pb-Pb, U-Pb, and Pb-Pb-calibrated isochron and model “age” for these achondrites cannot be their true real-time age, which according to the biblical paradigm is only about 6000 real-time years. “However, these conclusions and suggested explanations as discussed are still somewhat tentative, their confirmation or adjustment awaiting the examination of more radioisotope dating data for groups of meteorites, and martian and lunar meteorites. Furthermore, further extensive studies of the radioisotope dating of lunar rocks and rocks from all levels of the earth’s geologic record are required to attempt to systematize what proportions of the isotopes in each radioisotope dating system measured today are due to inheritance from the “primordial material,” to accelerated radioisotope decay during the Flood, and mixing, additions and subtractions in the earth’s mantle and crust through earth history, particularly during the Day Three Upheaval and then subsequently during the Flood.” Thank God for Dr. Snelling’s contribution.
