Sad, the point is supposed to be for a better understanding and for the truth of where we come from, atleast that is the impression I got.

Actually, more often than not, I think it usually is a combination of different theories that wind up "right" or "correct" rather, not everyone is going to hit the nail on the head, the problem is, not enough people have an open mind to accept or combine theories with their own.

I have cored may holes in concrete for my profession and it humbles me that these ancients can produce a smooth carved out perfect tube...
I cannot even get one with a core machine with a diamond toothed core bit....

Even though it's a bit dated it's still pretty good.
Several mechanisms have been suggested as responsible for the formation of the Altiplano plateau; theories try to explain why the topography in the Andes incorporates this large area of low relief at high altitude (high plateau) within the orogen:
1. Existence of weaknesses in the Earth's crust prior to tectonic shortening. Such weaknesses would cause the partition of tectonic deformation and uplift into the eastern and western cordillera, leaving the necessary space for the formation of the altiplano basin.
2. Magmatic processes rooted in the asthenosphere might have contributed to uplift the plateau.
3. Climate has controlled the spatial distribution of erosion and sediment deposition, controlling the lubrication along the Nazca Plate subduction and hence influencing the transmission of tectonic forces into South America.
4. Climate also determined the formation of internal drainage (endorheism) and sediment trapping within the Andes, potentially blocking tectonic deformation in the area between the two cordilleras.
5. Convective removal of dense lower lithosphere beneath the Altiplano caused that region to isostatically 'float' higher.

I thought thee In Search of series were the best.
They and Chariots of the Gods got me starting in asking questions
Erich von Däniken and Graham Hancock started me asking the questions, but they did not provide satisfactory answers. It's only in the realm of academe that I started getting a reasonable picture of our past...not as glamorous as alien intervention and such but ultimately more celebratory of human potential.
