Prehistoric Facts
Prehistoric, also known as prehistory is the time period before records were taken. Records are some form of written history so during prehistoric times there was no form of a writing system. The term was first introduced into human existence in the 1830s in France when drawings were found on cave walls. Sometimes prehistoric refers to the time since the Universe began but when most people talk about prehistoric times they are referring to the time since life began on Earth.
