Offering a radical new perspective on the Great Pyramid of Giza and all the structures surrounding it, designers of Giza intentionally arranged these massive structures to create an astronomical timeline recording catastrophic events in the past as well as warning later generations of the precise times of future catastrophes. Old Kingdom pyramids of Giza were created, ?not as tombs for the pharaohs and their queens, but as “recovery vaults” to ensure the rebirth of the Kingdom of Egypt after a global disaster.
