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?

It’s not that everything gets buried, it’s that stuff which happens to get buried is available for us to find. Moreover, people tend to live in places where sediment is being deposited (flood plains where floods deposit sediments; cities where people are constantly dumping trash and building rubble) and not in places which are being eroded (the tops of mountains.)
