Probably worth drawing this thread's attention to the debate over whether ancient Hindu texts mention nuclear weapons and atomic war. Up to the beholder whether that makes those texts sci-fi or not, I guess.
Example:
Gotham Chopra did that with what is now Virgin Comics: https://liquidcomics.com/
See the gorgeous Ramayan 3392 A.D. https://en.wikipedia.org/wiki/Ramayan_3392_A.D.
Also see the film Cargo, which turns mythological narrative into a rather watchable space opera https://en.wikipedia.org/wiki/Cargo_(2019_film)
But it would sound like boomer uncles to claim that there is mention of space travel or nuclear weapons in our epics. The astra-s are simply figments of imagination.
I was just bringing up something I thought was tangentially related without expressing an opinion on it
