Every great culture, over the millennia has imagined great weapons and unlimited godlike destructive power. You could, as you are doing now, retrofit our narrative on any of those if you wish. Make your own sci-fi fantasy. Those texts are not.

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)
