Science Fiction is not just about the future of space ships travelling to other planets, it is fiction based on science and I am using science as my basis for my fiction, but it's the science of prehistory - palaeontology and archaeology - rather than astronomy or physics.
— Jean M. Auel

In sci-fi convention, life-forms that hadn't developed space travel were mere prehistory -- horse-shoe crabs of the cosmic scene -- and something of the humiliation of being stuck on a provincial planet in a galactic backwater has stayed with me ever since.
Barbara Ehrenreich prehistory quote

Sadism is not an infectious disease that strikes a person all of a sudden. It has a long prehistory in childhood and always originates in the desperate fantasies of a child who is searching for a way out of a hopeless situation.
— Alice Miller

If we turn to palaeontology to tell us about our biological evolution it is to prehistory that we look for evidence of the evolution of specifically human patterns of behaviour.
— John G. D. Clark

The number of known human fossils only increases slowly. But the manner of regarding and assessing them is capable of progressing rapidly, as indeed it does. In the absence of any absolutely sensational discovery in prehistory, there is an up-to-date and scientific manner of understanding man, which is solidly based on palaeontology.
— prehistory quotation by Pierre Teilhard de Chardin
