hi you might try reading “king david’s spaceship” by jerry pournelle . its a great sci fi where aliens land and fight medievil knights (and lose)

Another gem in this vein is Dan Simmons’ Ilium Cantos. the Greek gods are superpowered metahumans who live on Olympus Mons on Mars and have advanced technology. It turns the Trojan War into a hard science fiction masterpiece.
