The photographer is the one making the photo, it is their skill in doing ehat I described above that directly makes the photo. Whereas your prompts, tweaking, etc. are instructions for an AI to make the scenery for you based on other people's artwork.
I actually have a better analogy for you...
If I trained a monkey to take photos, no matter how good my instructions or the resulting photo are, I don't own those photos, the monkey does. Though in actuality, the work goes to the public domain in lieu as non-human animals cannot claim copyright.
If you edit that monkey's photo, you own the edit, but you still don't own the photo because the monkey took it.
The same should, does currently seem to, apply to AI. It is especially true when that AI is trained on information you don't hold copyright or licensing for.
