Uh, I think you should look up the definition of "terraforming".
"Terraforming.
To transform (a landscape) on another planet into one having the characteristics of landscapes on Earth."
"Terraforming (literally, "Earth-shaping") of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to those of Earth to make it habitable by humans."
By definition terraforming isn't something done on earth, it's done on other planets. So no, humans have not been terraforming since the early days, and in fact never have.
@LucyNuggler: terraforming and geoengineering are both kinds of planetary enginerring differing only in the location at which the work is done. it is not that large a dictional stretch to use the two terms as if they were synonyms.
