I recall an interview where Reza Aslan described that History, in its present form, didn't always exist that way. That is the rigor, validation, and peer review wasn't present. Instead, it was a tool to convey an intuitive understanding, to "get the gist of" past events, cultures or conflicts.
Since people once thought the Earth was flat, I would assume humans linear understanding of time also went through an evolution of sorts.
- How has the cultural concept and treatment of history (and time) evolved to its presently understood form?
...or, how did History become History?
