Egyptians themselves tell us this:
Then Thoth, being the tongue of the Great God declares that, acting for the Lord Tem, he is going to make a Flood. He says: “I am going to blot out everything that I have made. This Earth shall enter into (i.e., be absorbed in) the watery abyss of Nu (or Nunu) by means of a raging flood, and will become even as it was in primeval time. I myself shall remain together with Osiris, but I shall transform myself into a small serpent, which can be neither comprehended nor seen.” Budge explains “. . . one day the Nile will rise and cover all Egypt with water, and drown the whole country; then, as in the beginning, there will be nothing to be seen except water.” 9
What all of this alludes to is that there seems to have been an ancient tradition that associates the construction of the earliest pyramids (the giant pyramids) of ancient Egypt as providing some form of protection (a form of “doomsday vault” or “ark”) against an anticipated deluge that the ancient Egyptians believed would destroy their entire kingdom, a great deluge that they believed to be imminent after they had observed that the path of the stars had changed from their normal course (i.e., that the Earth’s axis had been disturbed in some way). In building these giant, immovable “storehouses,” the ancient Egyptians could place within them everything that would be needed to help ensure that their kingdom and culture could revive and reconstitute itself after the worst effects of this anticipated deluge had passed.
In summary, anticipating an impending natural disaster that they feared would completely destroy their civilization, the ancient Egyptians set in motion a “national disaster-recovery plan” (Project Osiris?) that saw them, over a few generations, complete a series of pyramids (about sixteen in total) that would essentially serve as arks that they hoped would bring about their cultural revival after the worst effects of the anticipated cataclysm had subsided, a concept that is not too dissimilar to our modern Svalbard Global Seed Vault in the Arctic Circle, which was secured in 2008.
What is important to understand here is that the catalyst event that so motivated the ancient Egyptians to initiate this national disaster-recovery project (i.e., the building of the first pyramids) was quite separate from the anticipated disaster that the king and his astronomer-priests believed was to follow and that the pyramids were built to survive. As stated, the catalyst event that initiated the construction of the pyramids (according to these ancient sources) seems to have been a sudden change in the course of the heavens (i.e., a disturbance of the Earth’s rotational axis), and the king, in asking his advisors what this change in the heavens would mean, was told that it would (some three hundred years in the future) result in a great deluge and fire (drought). It was only upon hearing of this impending disaster that the king then ordered the immediate construction of the pyramids as places in which to secure those items that were deemed most important to enable the kingdom to flourish again after the worst effects of the anticipated future calamities had passed.
But did the king’s astronomer-priests actually observe some abnormal change in the heavens? Was the Earth’s rotational axis disturbed in some way, causing the stars to change their course, and was this event followed three hundred years later by a great deluge and drought? Well, something seems to have happened, and this will be discussed in chapter 7. The simple point here, however, is that whether the anticipated disaster actually came to pass is actually neither here nor there; the key point is that the ancient Egyptians as a result of their observations of the heavens, believed a disaster was imminent and were motivated enough by this belief to put in place measures to try to protect themselves against its catastrophic effects, to try to put in
