eli5 Why are historical/archaeology structures/evidence underground?

132 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?

Anything worthy that wasn’t buried , was either stolen, destroyed by nature (wind, floods, rains, tides etc) or were discovered long ago since they were easy to find on the ground.
Moreover, structures underground were better preserved than those above.
