Keltham is having similar thoughts! He'll wonder out loud about whether Golarion's gods know enough Law to do any significant editing? If the newcomers haven't read the transcripts for this part yet - or it was less clear from the transcript than in-person - Golarion humans were obviously copied off some ancestors or cousins of dath ilan visible from Golarion's multiverse, the same way Keltham himself was able to appear here. Keltham can eat Golarion food and that doesn't happen unless the proteins inside are the same and that requires common ancestry. Similarly, the humans here birth 50% women and 50% men, so nobody tampered with that part.
If anything Keltham's sort of surprised that people here aren't more edited. He wishes he knew what the gods' original edits to mortals were, whose reversion or failure was described as mortals gaining "free will". That would provide a lot of hint about what level of Law-editing the gods were capable of deploying.
He's guessing it was relatively shallow, though? Not really anywhere near the level of 'make a mortal from scratch'? Humans here wouldn't have shared ancestry with dath ilan if gods here could just make mortals from scratch. The fact that the gods' edits eventually failed, and that people basically turned back into humans afterwards, says that it was probably much more like imposing extra structure on top, and much less like really remaking and rebuilding things like a 'programmer' could do inside a 'computer'.
Well, that seems to square with the rest of reality as Keltham observes it. None of the gods here seem powerful enough to be freely wielding Law on that level.
