To date, the developmental stages of substance civilization in human society have gone through the Stone Age, the Bronze Age, the Iron Age, the Steel/Cement Age, and the Silicon Age based in the dividing standard (typical materials) proposed by one of the authors. Further, we believe that human society has entered into the Nanomaterials Age. The developmental history of nanomaterial, the evolutionary process of nanomaterials during the Silicon material age, and the reasons that the world has entered the Nanomaterials Age are analyzed and discussed herein. In addition, we have identified the time when human society entered the Nanomaterials Age. Therefore, the theory of six eras of the development of human substance civilization has a complete exposition.
