Archaeology is the study of past cultures through material remains. These material remains might be a majestic pyramid, a trashpit, or a broken tool. Everything is a clue, and archaeologists are like detectives, piecing together the clues to figure out what life was like long ago. Over time, most things from the past decay or get buried underground. Archaeologists often have to dig or excavate to find the clues.
