The word "engineer" has different etymologies in different languages. In English, this comes from the word "engine", which, in turn, from the Latin "ingenium" "talent, device." In Arabic and Hebrew, "engineering" and "geometry" are the same word "handasa". So an engineer is someone who draws blueprints, measures/validates them, and those blueprints are later used to create something. My guess is that it comes from the architects building the ancient Egyptian pyramids (a simple geometric shape). The first is more like craftsmanship, the second is more like modern engineering. Waterfall is Engineering Agile is Craftsmanship
