If inventing a way to convert nitrogen from air into chemicals qualifies as geoengineering, it isn't even close to being the first example. I.e. when the first hominid moved the first rock out of the way to get into the first cave, according to Morton's reasoning, geoengineering began. See: Wilkinson B. H. *Geology 33, 161 - 164 (2005)* *Humans as geologic agents: A deep-time perspective.*
