Onur Cobanli explains:
You cannot argue with this because I am technically correct well because artifact as a word, means anything made by people, in general also means not naturally occurring but of course there are many naturally occurring things that we can artificially recreate, anyways I like to extend this meaning to be anything made by self-aware intelligence, not limited to people. However, intelligence alone never builds things; there should be wisdom and desire to push the intelligence to come up with an idea, a solution; and that desire to come up with an idea and the process that follows is design. Design is the process of creating things; it is therefore the design that is the origin of the first artifact and it will be design that will be the origin of the last artifact.
