This is ludicrous. Historically, all cultures have tales and myths involving heroes and villains, including in religious texts. Is the illiad for 12 year olds? Is Arthur and the Round table (Le Mort de Arthur) or Jason and the Argonauts or the works of Ovid not stories of superheros? All cultures have had stories which have been transmitted orally, via song, via poems, via books and even gasp via comics.
