my city, the amazon driver for some reason can't find my house number and keeps dropping off the package at the post office.
There have been many ancient cities in the Amazon rainforest discovered through satellite imaging/LIDAR/other techniques, but before those discoveries large settlements in the area were considered legends and myths.
That how the Europeans never found the Amazon lost cities, because earlier explorers were looking for cities like European cities.
