The physics department at your local community college has used their time machine/transporter to pluck someone out of an ancient civilization from exactly 6000 years ago. You don’t know where they came from. From their hands, they appear to part of the lower class of whatever society it was.
You have been given your choice of tasks. You must either express to them the current year (IE, how far they’ve traveled into the future) or you must express to them their current geographic location. Which task do you choose? How would you accomplish your goal?
This is not Pawn Stars. You can’t call in your friend who is an expert in communicating with people from ancient civilizations.
I had no idea which forum in which to put this.
