"embalming rituals"

Explanation:

We must distinguish the historical origins of religion from its psychological or sociological origins. The first religious behavior that appears in the course of human evolution is likely to be relatively recent (Middle Paleolithic) and constitutes an aspect of behavioral modernity that appears surely at the same time as the origin of language.

The later development of religion embraces the Neolithic religion early in the history of religion with the early religions of the Ancient Near East (the polytheistic cults of Egypt and Mesopotamia).

While religious behavior varies widely among the different cultures of the world, in a broad sense religion is a cultural universal found in all human populations. Common elements include:

• a notion of the transcendent, the supernatural or the numinous that often implies entities such as ghosts, demons or deities and also practices related to magic and divination.

• an aspect of ritual and liturgy that is almost always accompanied by music and dance

• societal norms on morality (ethos) and virtue (arete)

• a set of myths, sacred truths or religious beliefs.
