Many, many, many years ago, there was creative story in Readers Digest along the basic lines of what would an archeologist say if they discovered rements of todays society thousands of years from now.I read somethingthing similar - maybe the same article - only it was about what they found in a church basement where community breakfasts and dinners were held. The archeologists concluded that we were cannibals and that there must have been some horrific rituals performed there.
I cant remember the whole thing, I was probably ten when I read it, but I recall it was funny, and it did make me think twice whenever I see archeologists label everything as a temple.
Same here. If they find an object that they can't identify or that looks too technologically advanced for the strata it was found in, they label it a "shamanistic" or "religious" device.
