Or detectives struggling to make sense of the ancient world based on tiny scraps of clues that have managed by sheer chance to survive for hundreds of thousands of years, usually in an altered state.

Sapiens 300,000 years ago, rather than trying to pin things to our present evolving knowledge base.
