On the Artifactuality of Humanity

While perhaps not directly related to art, I feel a need to explore this question: are humans artifacts?

A quick look in the dictionary will yield several definitions of the term "artifact," but all have a common theme: the idea of being "made by humans." How can humans, therefore, be artifacts?

In some part, humans are made by other humans in that it requires two humans to have sexual relations to create a new human. However, nature is also a large player in this process, and the humans who participated in the sexual act have very little influence on the being that is created (except possibly in the option of aborting the fetus).

For the spiritual, there would certainly be the argument that humans, and indeed all life, are the artifacts of the divine, be it one god or many gods, or merely a guiding divine force.

For the less spiritual, such an idea may well be absurd. Perhaps nature, then, is the creator, and we humans the artifacts of nature? That would, of course, require some anthropomorphisation of nature. But where is the harm in that? Worse metaphors have been spoken.

Could humans be artifacts in some other sense? Or is it absurd to think that something as complex as life could possibly be an artifact?
