I used [Gentube AI] to generate the image, and resized it to 8000x10000 px.

By @Phongsak Khantho

8000x10000px is huge and too much. I do not know the initial size of your assets, but you should limit the resizing, to get just over the minimal requirement of 4 mega pixels.

Did you compare your work with similarly key worded content in Stock BEFORE you submitted?

Stock customers expect the highest visual and technical quality for use in commercial projects.

Hope that helps.

Poorly drawn edges here

If it weren't for similar, a quality issues refusal would have been also a correct refusal reason, at least for the Mysterious Human... There are artefacts, colour clipping and exposure issues in this asset.

You were told what the issue is. "Similar content". Adobe feels that the submitted assets are to similar to assets already contained in the database.
