At some time in the past 8,000 years the planet Earth rocked and reeled on its polar rotational axis. The question is, did that coincide with Noah’s flood? And if so, can we determine from observational data when that was?

The rotational axis of Earth is tilted at an angle of 23.44 degrees to the plane of the planet's orbit around the Sun. How has it changed over the past 7,000 years? Is there evidence of an extraordinary event that changed it?
