burials with all kinds of grave goods. So people didn't just stick people in the earth. They marked the graves as something special. To give you one example, there's a 40,000 year old burial of a toddler in what's today Spain, with a hearth all around, 60 sets of oryx and bison horns, a rhino skull. This was a place that mattered. In some sense we can think of it as a sacred place. The question is, is there belief in an afterlife? Is there belief in supernatural beings? How would we know? We're imposing a great deal of our framework onto the past.
