1. Why do you think Harry Potter is or can be anyones "religious scripture"?
I don't think this is the case because nobody presents it as such. It is only ever presented as a fictional work for entertainment purposes.
2. What evidence do you have that Adam and Noah were fiction?
Several points in this one....
First, this is kind of a shift of the burden of proof. It's upto the one claiming they existed, to support said claim.
Secondly, if by "adam" you mean a single person who's the ancestor of all humans and who was "the very first human", then genetics contradicts that. Genetics effectively
disproves such an Adam in every sense of the word.
Same goes for Noah, if by "noah" is meant 1 of only 8 people who survived a specific cataclysmic global flood. This story makes testable predictions that do not check out. Again genetics alone already
disproves such a noah in every sense of the word.
And aside from these disproofs of those specific "interpretations" of the stories, there is to my knowledge zero supporting evidence for just about any interpretation of these stories.
So at best, we have stories that can't be disproven and which aren't supported in any way by testable evidence.
And in that sense, I guess you could compare it to the saga's of Lord of The Rings, Star Wars, Harry Potter,...
I mean... how would you go about disproving Harry Potter?
The claimant has the burden of proof, thus rather than committing the burden of proof fallacy, I would like to hear the mythicists argument on this.
Did my response satisfy you?
