True, you could say that although we passed our days in these parts, we didn't strictly speaking historically exist. Since we didn't have any writing to record our history, no one knows what we prehistoric peoples were really like. At most, we only left some broken pottery and old stones.
話又說回來，雖然我們曾經存在，但嚴格來講我們其實是「不存在」的；因為我們那時並無文字記載，沒有人曉得我們這些史前人到底是什麼模樣，充其量只留下一些破陶片、舊石頭而已。
