eli5 Why are historical/archaeology structures/evidence underground?

131 viewsOtherPlanetary Science

Earth as a whole is essentiallly a closed system right? Nothing leaves except what we send into space and (presumably) no material enters earth except the some space debris.
Where does all the earth/dirt come from to consistently bury historical structure under ground across the world?
