where did the tradition of burying the dead come from
Intentional burial, particularly with grave goods, may be one of the earliest detectable forms of religious practice since, as Philip Lieberman suggests, it may signify a "concern for the dead that transcends daily life." Evidence suggests that the Neanderthals were the first human species to practice burial behavior and intentionally bury their dead, doing so in shallow graves along with stone tools and animal bones. Exemplary sites include Shanidar in Iraq, Kebara Cave in Israel and Krapina in Croatia. Some scholars, however, argue that these bodies may have been disposed of for secular reasons.
