[Serious] How many reasonable solutions are there to any particular social issue?

[Belacqua]

On what basis are you claiming that cavemen had no religion?

It would be very interesting to know what kind of practices people had in the time that the Venus of Willendorf was made. Maybe you can tell us?

I'm very skeptical that people in those days divided their society along the same lines that we do. The idea that there was a set of practices they called "religion" seems unlikely. The probability that they had something they called "religion" in opposition to "science" or "government" seems small to me. 

Recent anthropological work indicates that people specifying something called "religion" as a separate part of their culture is surprisingly recent. And it is possibly a modern European concept that has been projected onto different cultures in the past and in other parts of the world. What we think of as religion would just be called "how things are" or "what we do." 

This is from Wikipedia:

A number of scholars have pointed out that the terminology used in the study of religion in the west derives from Judeo-Christian tradition, and that the basic assumptions of religion as an analytical category are all Western in origin. This idea was first raised by Wilfred Cantwell Smith in his 1962 book, The Meaning and End of Religion.[39] Among the main proponents of this theory of religion are Daniel Dubuisson, Timothy Fitzgerald, Talal Asad, and Jason Ānanda Josephson. These social constructionistsargue that religion is a modern concept that developed from Christianity and was then applied inappropriately to non-Western cultures.

While few would dispute that the concept of religion does have a historical genealogy, there is some disagreement about what the Western origin of the term has meant historically. Some such as Tomoko Masuzawa have felt that the equation of religion with Christianity had the effect of diminishing other traditions, especially in the study of comparative religions as it developed during the high point of Western imperialism.[40] Others[who?] have felt that this sort of criticism overestimates the influence that Western academic thought had on the rest of the world.

I know that some of the ways Buddhists and Shintoists in Japan characterize their religions came about as the influence of Christians, and that before such influence people drew the lines differently.
