In the chronicle of the Indian Hope Tribe in Central America, three disasters of prehistoric earth were recorded.
The first time was a volcanic eruption.
The second time, the earth spun wildly after leaving the axis. This is because the north and south magnetic poles disappeared, and the weather was extremely cold at this time. This period was the fourth ice age when the earth froze 10000 years ago.
The third time was a catastrophic flood, which was formed about 8,000 to 7,000 years ago after the Ice Age, and was recorded in ancient books of various countries during this period. In Western Europe, it is the story of Noah's Ark saving all beings in the flood, while in China, it was Dayu who subdued the catastrophic flood.
So we only know the time when they recorded the second time, because now the intersection of yellow and red is getting smaller and smaller, and the north and south poles are slowly approaching, so we can calculate the time of the second disaster, but the first time is unknown, so it is at least 10 thousand years!
