An analysis of the discrepancies between the Greek Septuagint (LXX) and the Masoretic Text (MT) concerning prophecies in Daniel 9:24-27, particularly about the Messiah, indicate corruptions were deliberately made to prophecies in the MT to minimize their fulfilment in Jesus Christ. This affects interpretations of Christ's role in destroying Temple worship in 70 AD.
What if the Bible by your nightstand has some serious corruptions? What if your Old Testament was not the Old Testament used by Christ and the Apostles? It isn't. And it does.
Young Earth Creation means the Earth is less than 10,000 years old. The biblical genealogies and historical records support this belief. I now advocate for the Septuagint's chronology as more reliable than the Masoretic Text, which has been corrupted. It follows then that the age of the Earth is about 7,580 years.
I model the decrease in human lifespans after the Flood due to a combination of factors beginning at the Curse, including divine sustainment, loss of physiological resilience and changes in Earth's environment. Current research indicates a hard limit on human lifespan due to physiological resilience limitations.
An examination of the ages of patriarchs from the Masoretic Text (MT) and Septuagint Text (LXX), highlights a significant decrease in human lifespans post-Flood. A correlation between Earth's axial tilt changes and lifespan variations forecasts that, without medical advancements, human lifespans will continue declining.
