OK, this was bothering me back that the turn of the millenium. Who or what do you think had the most significant reach and impact of that last millenium? For me, I think the Chinese had the most impact. In regards to person impact, local impact, governmental impact and global impact. The Chinese inveted fireworks which led to guns. The Chinese also invented paper. Ts'ai Lun, is credited with inventing paper circa 104 AD. I think just in those two inventions, the Chinese forever changed the way the world worked. Anyone else have a vote?
