Dating methodology for the Vishnu Schist

Welcome to the fray Centrus. Is based on the radioactive decay of 14C, which has a half life of ~5700 years, and the limit of any object being dated by 14C methods is ~50,000 years. Further 14C can only date organic samples, as it is dependent on the organic accumulation of atmospheric 14C to provide the base level from which the decay is calculated. If you are interested in the validity of dates, I can suggest a review of Age Correlations and an Old Earth: Version 1 No 3 (formerly Part III) and Correlation Among Various Radiometric Ages (see Message 5)For a good review of the geology of the Grand Canyon, I recommend Exploring the Grand Canyon, from the bottom up.The big issue, imho, is whether you will consider all evidence on the table or deny that some is valid. The different concepts have different filters for "truth" and many YEC (young earth creationist) models rely on ignoring ample corroborated evidence for an old earth.This still leaves OEC (old earth creationist) models and theistic models.We no longer see claims of earth being at the center of the universe, because there is just too much evidence that the earth orbits the sun in an outer arm of a rather common type of galaxy in a universe with many different and varied galaxies.The biblical interpretation that led to this geocentric claim is no longer in vogue because of this overwhelming evidence that refutes it.The evidence for an old earth is similar. I believe the effect of this reality on the various world religions will also be similar.Once we've dealt with the age issues then we can proceed to the evolution issues eh?Enjoy.
