Sure, this sounds like a pretty simple task. You might be happy to know that I’ve already found plenty of data. It looks like the oldest historical records of civilization date to around 4000 BCE in Sumeria and the Indus Valley.  Were you wanting me to show you data in order to make sure I understand your request?
