Meteorites have been used to date the earth with a 4.55 ± 0.07 Ga Pb-Pb isochron called the geochron. They appear to consistently yield 4.56–4.57 Ga radioisotope ages, adding to the uniformitarians' confidence in the radioisotope dating methods. The Allende CV3 carbonaceous chondrite meteorite, which fell to earth in Mexico February 8, 1969, is one of the most-studied meteorites. Many radioisotope dating studies in the last 40 years have used the K-Ar, Ar-Ar, Rb-Sr, Sm-Nd, U-Th-Pb, Lu-Hf, Mn-Cr, W-Hf, Al-Mg, and I-Xe methods to yield an abundance of isochron and model ages for this meteorite from chondrules, Ca-Al inclusions, whole-rock samples, and matrix, mineral, and other fractions, all of which components are described. The age data were all tabulated and plotted on frequency versus age histogram diagrams, and strongly cluster at 4.56–4.57 Ga, dominated by Pb-Pb isochron and model ages. The earliest (1976) and the latest (2010) determined Pb-Pb isochron ages at 4.553 ± 0.004 Ga and 4.56718 ± 0.0002 Ga respectively are essentially the same, testimony to that technique's supremacy as the uniformitarians' ultimate, most reliable dating tool. Apart from scatter of the U-Pb, Th-Pb, Rb-Sr, and Ar-Ar ages, no systematic pattern was found in the Allende isochron and model ages similar to the systematic pattern of isochron ages found in Precambrian rock units during the RATE project. If such evidence in earth rocks is applied to meteorites, then Allende seems to have no apparent evidence in it of past accelerated radioisotope decay. However, if accelerated radioisotope decay did occur on the earth, then it could be argued every atom in the universe would be similarly affected at the same time. Furthermore, meteorites are regarded as primordial material left over from the formation of the solar system, which is compatible with the Hebrew text of Genesis that suggests God made primordial material on Day One of the Creation Week, from which He made the non-earth portion of the solar system on Day Four. Thus today's measured radioisotope composition of Allende may reflect a geochemical signature of that primordial material, which included atoms of all elemental isotopes. So if some of the daughter isotopes were already in the Allende meteorite when it was formed, and if the parent isotopes in the meteorite were also subject to subsequent accelerated radioisotope decay at the same time it occurred in earth rocks, then the 4.56718 ± 0.0002 Ga Pb-Pb isochron "age" for the Allende cannot be its true real-time age, which according to the biblical paradigm is only about 6000 real-time years. The results of further studies of more radioisiotope ages data for many more meteorites will confirm or adjust these tentative interim suggestions based on these Allende radioisotope ages data.
