How do I find the original artist in this mess?

I almost never shop on Etsy anymore since it has become a drop shipping nightmare, but I wanted to find a fun Project Hail Mary shirt. Well, I found a bunch that all seem to have ripped off the similar design.

Does anyone know how you can hunt down the original artists in situations like this? I'm assuming there was one somewhere (maybe they didn't even have the artwork on a shirt). Reverse image search has failed as it just pulls up more copy cat sellers.
