Our buildings are on dry land. Dry land is dry because it's predominantly made of continental crust [1]. It's lighter than oceanic crust [2]. When oceanic and continental crusts meet, the oceanic tends to get driven under the continental crust, which floats on top. Keep in mind that we still have fossil shells feom 65 million years ago.
