Religion cannot be reduced to “behavior towards supernatural agents”, which are “personalities whose existence is believed but cannot be proven scientifically”, i.e., personalities whose existence cannot be proven empirically. The worship of the sun in ancient cultures does not fit in the “non-empirical status” of the supernatural agent, as defined above: the existence of sun was easily and empirically verifiable by those ancient people who worship it ― and we cannot say that the Egyptians considered the sun as a “person”; they knew the sun was something similar to the moon and to all other astrological bodies they use to analyze through their astrological charts inherited from the culture of the Babylonian Zigurats.
The very first thing we must do when analyzing religion throughout human existence ― and not necessarily throughout human history ― is to divide it into two different kinds: the immanent and the transcendent religiosity. Most cultures mixed both criteria. In the case of the worship of the sun, the religion was immanent ― the object of worship was something concretely and/or allegorically belonging to the universe and appertaining to its logical order. Even the Greek gods were immanent because they were intracosmic and symbolized the human phenomena and life. However, alongside with the immanent, most cultures also worshiped the transcendence and the domain of the only master God who created the Cosmos (cosmos= “The Order”) and “after the Creation moved away from human presence and existence”, leaving to the immanent gods the task of ruling the Creation of that “master transcendent God”.
All books of Mircea Eliade are indispensable reading for someone analyzing the religion phenomena.
The problem of biology and neurobiology is that those scientists created a world for themselves, ignoring other scientific data as those coming from quantum physics. Sometimes, neurobiology seems to evolve itself to a sort of “neo-phrenology”.
Those neurobiology scientists are absorbed and exclusively focused by the “research of the effect” (epiphenomenalism) instead of taking into consideration the “causes” by linking their investigation fields to other scientific fields as quantum physics. They simply forget that our brains exist as a structure according to the same principles driving the quantum wave function. They also forget that according to quantum mechanics, quantum waves (which are not matter as the waves do not have mass) transform themselves in particles (matter, because with mass) when observed by a [human] conscience (see Bernard D’Espagnat). What we see in science is that physicists are clearly saying that neurobiologists are dumb; and the latter disregard the categorization and remain proudly in their dumb world.
A neurobiologist may be compared to a guy that is ― in a very dark overcast night ― looking for his lost car keys bellow the street lamp, inspite of the fact of having loosed them ten yards away from the light spot, and because there was no light available on the real spot where he lost the keys. However, they consider themselves as the most-super-intelligent creatures on Earth.
Any comparison between a human being religiosity and the music of the whales and the so called “culture” of the high apes, is irrational because it implicitly considers a sort of “human rationality” either in whales and in apes. The neurobiologists really start from the concrete reality ― or from a real, concrete and objective fact ― and throughout a serial of erroneous induced and deducted thinking ― with an intrinsic logic, however ― they reach to a faulty constructed reality which they call “scientific”.
