The word 'prehistoric' is used to describe something that happened, existed or occurred a long, long time ago, before events were recorded in history. It is used to describe the time period before written history began. For example, when we talk about the Prehistoric Era, we are referring to the time when humans lived in caves and hunted animals for survival, before there were any written records of history. The word prehistoric can also be used to describe something that is very old or out of date, like an ancient tool or an outdated technology.
