If we're using the metric of the lifespan of Chinese civilization which has cycled through shorter-lived regimes and empires, American "civilization" would clock in as approximately 0.4 of a millennium old. OR if we consider it an extension with "western civilization", the continuity goes back about 2.5 millennia, though still a lot younger regardless.
