Left to ponder structures such as the Giant Pyramids or Stonehenge or the Sphinx, man invents theories and tried them on for a fit. If one finds a dead elephant in
the town square, it could be an escapee from a passing circus, a prank, or an evil omen. Unless the exact source or reason is determined, any and all of those
theories continue to circulate. This is the nature of problem solving - putting forth theories and then testing them. If a theory cannot be disproved, then it is not put to
rest, regardless of its validity.
In that pyramids were a burial site for Egyptian rulers, the Giant Pyramids were first assumed to be mega-burial sites. This theory flew until astronomical sighting tunnels were discovered, but the original theory still circulates. Folklore states that the Giant Pyramids were a sighting device pointing toward Orion, originally, and this is correct. Now, due to movement of the continents during pole shift, it no longer points there, but the Giant Pyramids seem to align North and South in a precise manner. So new theories emerge. Why would the ancients need such a device to locate north and south, when a simple sundial marked with the seasons would have sufficed? Had the Giant Pyramids not lined up in this manner, at present, then whatever the alignment happened to be would find a theory emerging to explain the purpose of the Giant Pyramids.
Passing Stonehenge through the astronomical sighting theory, all manner of peeping in this or that direction occurred until some correlation with an astronomical body emerged. Ahah! It lines up with the Moon, at present, so was a planting guide for ancient farmers, who in any case hardly needed a device such as Stonehenge to observe the Moon and its phases. Stonehenge is very ancient, and was a structure constructed by aliens in the Service-to-Self to strike fear into the primitive hearts that observed it. It looks like a site of satanic worship, for human sacrifices, and this reminder of such horrors was to be ever there, which it is in the main, today.
The Sphinx stands as a massif staring out over the sand, like a guard. What is it guarding? Is it looking at or away from what it is guarding? Theories abound. The Sphinx was a burial chamber for a giant hominoid of great renown as a hunter of lions, though his body never made it to the burial chamber. However, since those who could stand witness to its purpose are long dead and left no written explanation, they cannot be proved or disproved. Therefore, our explanation, like all other theories, remains unproved yet not disproved, and therefore will circulate along with the other theories endlessly.
