The oldest sacral building is probably the ritual area. Nabta Plaja (100 kilometers west from Ab=FA Simbilu) constructed at Sahara wild about 2000 years before building the first pyramid. The religious center consisted of eight great barrows, thirty stone cromlechs built above deep delves and three series of menhirs oriented out of one point. Archeologists have mentioned that ritual center of mysterious buildings was built for annual celebrations of coming the solstice and life giving rains. It has been very much simple and incorrect explanation, but we may not be surprised, for absence of information cannot be answer differently.

For mentioned building is impossible to give reasons by one sentence, in the further text I will try to do it and I am beginning by the question: "Can be the identical area reared anywhere at other place?" It can be answered that it is possible, but the area will not be functional. The basic condition for it is building at "an exquisite place". Where such places are situated is not known all-round, they can be found on plateau Nazca. There the builders of uncanny constructions visualized at large surface zones of energy raster of cosmic energy that is situated throughout on the earth. The choice places are so energy zones that can transfer their energy to another mass inclusive to organisms. Zones produce natural sources like sea streams, other watercourses inclusive water wells, mineral deposits, forest complexes, squally clouds, etc. A mineral placed in a zone receives from it the energy. The mineral has turned into a menhir and if we place it out of zone, some few hours it will lose the assumed energy. Those are fundamental information without cannot be evaluated the ritual area Nabta Plaja.

Eight large pyramids on the building site accumulated the cosmic energy like the mass of zikkurats, pyramids, mounds, mosques, cathedrals and further resembling buildings. Major density of zones inside constructions especially circular operate like energy magnifier, walls of earthy hollows generate the same effect. Energetic capacity of choice place can be piled up not only by another mass, but also by shaping. Obelisks, poles, menhirs, steeples, and other tall constructions obtain the energy partly by charge flux and also thereby, that their construction intersect three-dimensional zonal raster. The cromlech from sand blocks, built above a hollow, accumulated in its mass the energy as well as menhirs and concentrated the energy of sanctuary by the energy of columnar effect. Three series of menhirs were built for an interception and an induction of further energy to choice locality. In later time functioned the rising ways of pyramidal complexes or artificial watercourses below plateau Nazca on the identical principle.

From the standpoint of my research have the subjects of religious center Nabta Plaja the energetic quality identical like other sacral buildings built in later times. The eldest religious center in Nabta Plaja can be thus evaluated so, that it was constructed at the place with energy overstrain. By the piling and shaping of mass was enlarged its energy capacity having positive effect for the visitors of sanctuary.

The unusual evaluation of technical level of long past cultures is not conformable with known facts, but is it necessary to respect, that the transitions of energy can be proved by experiments. Lot of people has supposed that unknown technically advanced civilization anticipated to chronology of old cultures. Scientists have responded to it so, that till this time not a single article had been found to prove it. Plurality of megalithic constructions, by which has not been found their purpose, can be regard as testimony, too.
