We build out of concrete now days and those will last thousands if not millions of years. A number of structures built by the Roman's out of concrete are in fine shape today and even earlier concrete structures still survive. Link to comment Share on other sites More sharing options...

So lets see those same Egyptians make a skyscrapers out of glass and steel, with modern plumbing and electricity and see how it lasts. Link to comment Share on other sites More sharing options...
