I think the answer is President Monroe
Americas and Oceania were similar in the way that first they both could developed experienced agricultural practices. Second, they could have their own distinct architecture, art and some other cultural characteristics with any influence from the outside. Third, some external groups sustained their nomadic hunter.-gathering lifestyle. And finally, both of them faced dangers of overpopulation and exposed of diseases they had never been exposed to. They both were different just because they developed large sophisticated societies in isolation merely.
(Take this response with a grain of salt.)
I personally think that neither should determine that. Both questions are unable to determine whether the religion is true; so why would it be used to determine whether or not people have the right to follow it. However, putting that aside, I think the best answer would be how good their followers are. It doesn't determine whether the religion is true or not but it rids us of the toxic religions that spread negative messages. Considering how much racism, homophobia, transphobia, and sexism is in most religions it'd be interesting to see most religions cease.
Including commonly followed religions like Catholicism.
