Imagine if tens of thousands of years from now, archaeologists were to dig up a pile of wrecked, 20th century cars and try to figure out what people did with the strange-looking things.
After measuring soil-encrusted automobile shells and scattered engine innards, the researchers might well announce the discovery of ancient religious altars. Support for their interpretation would come from fragments of 20th century texts describing widespread car worship. Eminent scientists might propose that basic altars were made in a city called Detroit before being modified by their owners into objects suitable for worship. A flood of publications would sort the artifacts into categories of altars based on the presence or absence of tail fins and roof racks.
