> how come so much stuff is buried? Tombs of course. No, that's not the reason. Rather it is the case that through most of human history new buildings were built on top of the rubble of earlier buildings destroyed in a fire, sacking, earthquake, or in very early times the simple accumulation of trash. In many parts of the Middle East finding a lost city is as easy as looking for a hill that has no geological business being there and digging. People living in the same place over thousands of years is what makes the hill.
