I read this story in the 70s; is about an astronaut running from the law, he crash landed in a "deserted" planet and got badly injured, to the point that he cannot move at all.
Then this small creatures appear and tend to him, learning from him and developing a culture around him.
Later on more humans discover the planet and the creatures and find a statue of the man build by them.
I think Futurama did a sketch about it.
What's the name of the story?
