America doesn’t have much of a traceable past. Not only are we a rather recent addition to the list of nations, but long ago remnants exist only if they were built of stone.
Who know how many civilizations came and went on Earth without leaving traces because they built their cities from wood or adobe?
Old means very different things here and there.
Now we build cities and steel towers. We’ve created piles of rubbish that will never decay.
A thousand years from now, archaeologists may believe we worshiped aluminum cans or plastic bottles. Because that’s what they will find.
