It is the traditions that are about death that give the earliest evidence of religious beliefs. Scientists have discovered that 120,000 years ago, Neanderthal people started burying their dead. Early Homo sapiens put tools and other things into graves with the bodies, as if they could use them in the afterlife. From 40,000 years ago, many of the objects in graves are small artworks. Scientists believe that these objects were put there for religious reasons.
