If I commission a human artist to paint me a picture or write me a song, did I create it? I gave them the prompt to generate the work with their skills, so I must be as creative and skilled as any work they return, right?

You’ve asked something else to make your art, and then claimed that because you were really specific with your request that you deserve the kudos for the creativity and skill of the art. Pick up a pen and stop stealing existing artists’ work in order to force a computer to stroke your delusional ego.
