Right now, the Sin Eaters seem to be the most likely origin (even those on the First mistook them as holy beings, at first), and that's why folks have been speculating as to how the Amdaporians could possibly have known about them.
If it's eventually canonically established that there's NO link between the Sin Eaters and the Amdapor golems, then we'll STILL be keeping an eye out for whatever transcendent beings the golems really were modeled after. But I really do think the Sin Eaters are meant to be that answer - so the question now, is, "how?"
