In my opinion, the Biblical flood of Noah occurred during the 5.9 kiloyear event, around 6,000 years ago, coinciding with an anomaly or sudden drop in Earth's magnetic field, the desertification of the Sahara, and the Y-chromosome bottleneck, during which 19 out of 20 male lineages went extinct.
Another two possible dates are the 8.2 kiloyear event or the Younger Dryas period. However, in my opinion, the Biblical narrative begins 6,000 years ago with the start of the Age of Taurus, following the Biblical Flood.
This event is what destroyed most of the population and marked the beginning of the current Kali Yuga, or the Iron Age—the long winter in the Great Year. Deep rabbit hole thread! (1/9)🧵
