@farmerman,
Interesting, that you see Animism as the focal point for the beginning of an assumed afterlife. My Latin is forever rusty but serviceable enough to translate 'anima' for animism which Milton later translated to 'soul' or mind and spirit.
Perhaps you can agree that the earliest known burial of Homo at Qafzen Jebel roughly 190,000 years ago could just as easily be a case in which the burial was for personal safety as early Homo had learned that decomposing humans attracted predators and scavengers? As far as 'trinkets' as you so describe there is no way of really proving that this was done deliberately.
Any talk of religion in the worlds history often get to the point of absurdity as how in the world could have the Brits has gotten so far removed from reality that they burned people to death in public as so the population would not stray from the company policy.
It often, for myself anyway, leads me back to Cheech and Chong's hippy who proclaimed that : "Before I was all messed up on drugs-then I found the Lord-now I am all messed up on the Lord"
