One of the things that make humans unique is their ability to make and use tools, and ever since the first rough stone axes began to appear about 700,000 years ago, human cultures have left behind artifacts from which we've tried to draw a picture of their everyday life. The roots of artifact mean basically "something made with skill;" thus, a mere stone that was used for pounding isn't an artifact, since it wasn't shaped by humans for its purpose—unlike a ram's horn that was polished and given a brass mouthpiece and was blown as part of a religious ritual.
