Universal numbers have been entwined into mythology and megalithic structures long before modern religion.

'The Great Year' is the length of time for the constellations to complete one rotation.  (also known as the Platonic year). Somehow ancient people figured this precession out.

The number is 25,940 years.

Derivatives of this number are found throughout the universe.

1 degree is 72 years (ie the constellations cross the night sky 1 degree every 72 years, meaning it would take many generations to observe one cycle.)

This cycle is replicated in smaller doses many many times - cycles within cycles.

The body of work and the tangents that stem from this are too many to describe. Suffice to say that it informs my take on religion; all stem from the memory of a near extinction and the base narrative is designed to tell us the how's and why's to repopulate and survive. This is common to ALL religions (flood myth, cataclysms, repopulate, treat each other). Later add ons and lies are the works of people looking for power and not for the crucial survival of the species.
