Many writers get lost in wanting to attribute a deist philosophy to the Náhuatl race, when their cosmogony tells us otherwise.
They understood a creative being, Ometecuhtli, but that creator was the element of fire (matter), and the creation occurred by the fact of omeycualiztli (matter). The cretaor was the eternal (Ayamictlán), but the imperishable continued to be fire (matter). The gods are the four material beings, the four stars: Tonacatecuhtli, Tonacacíhuatl, Quetzalcoatl and Tezcatlipoca. They deified the rains in Tlaloc and the sea in Chalchiuhtlicue, these deities also being material. To explain the appearance of men, they resorted to the action of fire on earth (matter again), the marriage between Tonacatecuhtli and Tonacacíhuatl. The idea of a spiritual being was not perceived.
The Nahuas were not deists, nor can it be said that their philosophy was Asian-pantheism. It was materialism based on the eternity of matter. Their religion was the Sabaeism of the four stars, and like their philosophy, it was also materialistic.
This is one of the most difficult things to get when building your startup. At the beginning you have no way of getting accurate costs, and clearly, there's no one-size-fits-all approach for this.
Right. Energy analysis is cool, but it places a lower bound on the amount of work needed, that's all.
If you're only counting energy needed to raise stones, then you're costing at zero a piece of stone, cut and transported to ground level near the pyramid. But that is hard work.
