A half-million-year-old hominid skeleton, found deep in an Italian cave, opens this look at how early humans began to think and feel like people rather than animals. The film moves from that skeleton to the painted caves of the Stone Age, asking what state of mind produced images that have survived tens of thousands of years. Researchers compare European cave art directly with rock paintings from South Africa, and the film travels to Namibia to film trance-dances among Bushmen communities, using the ritual as a living model for what the ancient painters might have been doing when they made their marks. The argument built from these comparisons is that the paintings are not decoration but evidence of a spiritual life recognizably like our own, tied to altered states and shared ritual rather than simple record-keeping. Reconstructions of early hominid life sit alongside the fieldwork, tracing a line from bone and pigment to something closer to belief. The film treats the emergence of family bonds and shared meaning as part of the same evolutionary story as tools and hunting.
