The motivation for the construction of menhirs, dolmens, cromlechs, mounds, stone mans and other similar structures was usually explained by astronomical, calendar, agricultural and ritual motives. We can't wonder that other arguments couldn't have been offered by known facts.

But there are even more mysterious megalithic structures - thousands of stone spheres that weigh more than 15 tons. They are located in Costa Rica and in other parts of the American continent and some even close to the North Pole. The arguments for their existence weren't persuasive but I agree that it's not possible without the knowledge of ether.

A rock in the shape of a sphere that is located in an etheric zone is energetically activated and becomes an independent source, which sends spherical zones out into surrounding space. These cross other energetically stronger etheric zones, interact with them and by their conductive properties bring greater amount of cosmic energy to the place where the stone sphere is located. It is probable that heads of Olmeks that are made from stone and have similar mass could have had similar function. In Nazca plain the etheric zones are marked in the flat terrain.

The water flows that were built underground were built to connect individual zones so that the energy could be transported to another place. Verification that shows that the zones in the Nazca plain were made energetically stronger are the rows of stones located very close to some zones (the stones are in interaction with the zone).

The present architecture isn't interested in the energetic of the structures and some structures could be so called "cancer houses" or could just slowly negatively affect their inhabitants. Sceptics could say that the steel constructions of skyscrapers and their height must show the negative effect more markedly.

The answer could be found in history, when people on the American continent built more than hundred thousand mounds, they cared a lot that the clay mounds weren't built on subsoil made from rock and they carefully isolated them by means of organic matter. When building mounds in Europe, the same technologic progress was abided. When constructing skyscrapers, we can't even imagine that they would be built in another way than on solid subsoil made from rock. We can deduct that the contact of the structure with the seam works in the same way as grounding by the fact that it drains the energy away into the ground.

However, it could be different with some low-bed structures that were built on earthen seams. In these connections it could be interesting to find out statistically the death rate in different hospitals. It's not easy to believe the fact that ancient people already had the knowledge about etheric energy that our civilisation will now only start to learn. The twentieth century, when thousands of scientists unsuccessively tried to resolve the mysteries of megalithic culture proves that the explanation is not in the region of known facts. Therefore we looked for the answers of puzzles of structures somewhere else.
