If that were the only plot then yes. But I assume there would be some interesting questions as to how similar or different the creators would be, what kind of physics they would have, how would "our" people react to the idea that there finally was proof of "God" who had crated us. And would that God be "good"? Personally here's one trait I'd like to see in the book: The weirdness of quantum mechanics gets even weirder as we study it more. And that is the clue that many take to mean we probably live in simulated reality because simulated reality need not be logically consistent. So in the simulators' reality there would be no Quantum Mechanics, and physics would be much simpler. In our simulated reality it exists only as a clue to us that we live in a simulation. Or something like that. Thanks for links to everybody, I didn't expect there to be so many books. I thought living in a simulated reality was a rather new idea. But Sci-Fi can see into the future.
