Keywords denied in new PS

I am trying to create an image using the new AI in PS. The goal was to see if I could create an asteroid strike on the moon with something of an explosion effect. When I use keywords that, I guess are interpreted as too violent, PS won't allow those actions. I understand how Adobe is trying to protect itself from nefarious forces trying to do bad things with the software. Still, I am wondering what options I may have in trying to create the image I am striving for. Any suggestions would be helpful.

Note: I am a terrible graphic artist, so trying to create the imagery on my own is not something I have been successful at. If I was, I wouldn't probably need the AI.

Thanks
