Thoughts On Ancient Cosmology

I must admit that I was fascinated by Walter Cruttenden's recent article on Reality Sandwich: Ancient Cosmology: A Map of the Future?

The article dealt with cosmology, specifically the notion that our cosmological history may in fact be cyclical, rather than linear, as contemporary science assumes it to be. This cyclical development is theorized to be the result of a large celestial shift, much like our own Earth's orbit around the Sun, but on a larger scale. This "shift" is said to correspond to the precession of the equinox, lasting roughly twenty-six thousand years. The specific cause of this cycle is not presently known, but possible explanations include an as yet undiscovered tenth planet within our solar system and the possibility that we actually live within a binary star system, rather than one containing a single star.

Cruttenden's assertion is that just as our consciousness cycles with each shift from day to night (from a waking to sleeping state), and the Earth's "consciousness" shifts with each passing year (regions transitioning from a bountiful, blooming state to a dormant one), so too does our overall level of consciousness rise and fall. However, because this ebb and flow spans nearly twenty-six thousand years, it is a cycle which is not readily visible to humans, one which we are simply not aware of. However, according to the article ancient societies were well aware of this cycle and the passing from age to age. It is believed that up to 40 separate civilizations included this system of ages within their cosmology.

I read this article a week ago today and have been thinking about it ever since. It brought a couple of ideas/questions to mind:

Firstly, if this knowledge of a great ebbing and flowing of conciousness has been all but lost and is now being rediscovered/repopularized, is this loss considered to be part of the cycle? Put another way, is a loss of this knowledge just part and parcel of transitioning through a "dark age," and the regaining of this insight a necessary wrung on the ladder of higher conciousness?

Secondly, I couldn't help but speculate on the existence of so-called "mysterious" sites which may have been built to serve a higher purpose, or whose purpose in unclear to us modern folks. Take the great pyramid for example, some think it was a stargate, some a microwave transmitter, some a powerstation, the list goes on and on. I have no such thoughts on the matter, other than that things seems to have some interesting design features which, as far as I can tell, extend beyond the rubric of a tomb. It's interesting to consider that such sites may indeed have been powerful tools, but that their usage requires the advanced consciousness that would have been possessed by the civilizations that constructed them. Furthermore, what if they do have a purpose, but one we haven't conceived of, perhaps a purpose that is only evident to the enlightened? For instance, if human evolution saw the slow depletion of water from the Earth, and we somehow adapted to live without it completely - eventually seeing every trace of liquid evaporate from the planets surface - far fetched, I know, but were this the case, would a civilization whose never known of water be able to ascertain the purpose of a site such as Hoover Dam were they to unearth it thousands of years in the future?
