I was watching documentary films about ancient civilizations and they made me wonder..what are we building in our time? in these days (meaning of in these centuries) which will stay on this planet and thousands of years from now people will look at them and guess what we made them for.. I also wonder what would you build if no money/time would matter just the reason to leave something behind or maybe you would have a specific reason for it, maybe a use of it for now or in the future.. We have seen cave arts..pyramids, ancient ruins like stone henge,nazca lines in the desert of Peru..Roman and Greek temples..etc
Hard roads,in particular motorways/highways. Military bases - built to withstand heavy attack,so they'll last a long time.
Missile okorder / Ithink I would like to leave written journals with plenty of photos of what life is like right now. Photos tell a lot that language can't. Iwould show and record, homes, hospitals, schools, military, wild life, cities, transportation, buildings, clothing , food.
