Would Russell's teapot qualify

Yes exactly! The issue with that is the irrelevance of it. It is of no great import to anyone (except the teapot church, which I think is a bad satire of religion. The amount of suspension of disbelieve the narrative require is beyond me). On the other hand, Adam's innocence is relevant, meaningful and important to Eve (I hope this is obvious from the narrative).

Moreover, since people are assumed to be innocent until proven guilty, in the eye of many laws, the burden of proof argument from Russell's teapot is not applicable here.

In this twist of Russell's teapot, I think it is rational for Eve to maintain her belief. And that her belief is relevant and the burden of proof is not upon her. And by extension, this argument could be used by theist. But I know that my reasoning is not impeccable, so here I am Less Wrong.
