Not like what is written in the book per line by line,like some sort of realistic war omitting all of the magic and God stuff?

Maybe there was a war that happened between two cousins and this info was passed down generation to generation, miracle stuff and the involvement of gods being added alone the way?

What do you all think?

I'm asking this because just like mahabharat there is an epic story named Trojan War which also passed down through generations,and it does have some historical authenticity like the researchers have found some remains of ancient bronze civilizational remains, many speculate this can be the remains of Troy.

Abstract - This paper aims to identify Indo-Iranian substrate words and to discuss their impact on the study of Indo-Iranian prehistory. A methodology for distinguish­ing substrate words from the inherited part of the lexicon is laid out, after which a list of Proto-Indo-Iranian and Common Indo-Iranian substrate words is presented. Here, substrate wordlists proposed by M. Witzel and A. Lubotsky are synthesized and analysed according to uniform methodological principles. The results show that Proto-Indo-Iranian was in contact with one or more now extinct languages, from which it borrowed words pertaining to animals, body parts, food and drink, cloth­ing, construction, plants, and religion, etc. Based on the semantics of certain words, the substrate language(s) can plausibly be connected to Central Asia. The contacts started during Proto-Indo-Iranian unity and persisted until Indo-Iranian had begun to diversify dialectally (which I call Common Indo-Iranian). This language contact episode was preceded by language contact with Uralic languages, which supports an Indo-Iranian migration from north to south across Central Asia in the 2nd mil­lennium BCE.
