I thought all of the places mentioned in Bible stories were lost cities that had been abandoned or destroyed a long time ago and nowadays we were not sure of their exact locations, like Troy before its rediscovery. (Except Rome, I guess, I knew there was still a Rome.)
And yes, this is true of some ancient cities, but people still live in Jericho, Bethlehem, etc. and they have for thousands of years, so it’s not a mystery where they are.
