ABSTRACT
The early history of humankind and its technological development is necessarily recorded in terms of vague memories and suppositions. The rise of humans is sometimes entirely cloaked in mythological tales based occasionally upon parallel conditions in contemporary societies. More advanced cultures had only to compare their own state with that of the primitive peoples with whom they had contact to comprehend that they themselves had once been a simple society. This development of primitive peoples into more complex civilizations was explained by a variety of methods.
