Sidney Austen's "The Frightened Planet" (short story, free): Stone-age earthman helps aliens regain their lost empire
Caution: Story include commentary on male/female relations that violates modern sensibilities.
Story summary.Karn of Tur, a stone age earthman, alone in the wilderness after a fight with his cave leader, will end up saving the lives of 3 visiting aliens from wild beasts & then traveling with them to their world, Mahlo.
Now Mahlo is a degenerate world. Space-faring folks with great cities are basically cowards, & quickly fall to spear-wielding lizard-men ("Green Ones") from their jungles. Karn will teach them bravery & help them regain their world back.
