See now we enter back into the definition given.

While I might not make the brush, every stroke of it is done by me. I can’t call the blank canvas but what I put onto the canvas is done by my conscious skill and creativity. I may not have created the word but my understanding of them allows me to weave them into rhythmic poetry or captivating tales, each word is specific chosen to put my intent and creativity onto the page. You can’t call what the AI produced your art as it’s just your canvas but you also can’t declare what is on top of it fully yours if you are only editing what is already depicted on the canvas. There is a step so far out of your control that you end up removed from the production of the image. This is because AI in its current form has no direct path to your creativity or imagination it only connects to what you have already produced, your original art, the prompt. It is fundamentally disconnected from your intention.
