During an interview in January 1971, when asked whether the stories take place in a different era, Tolkien stated, "No ... at a different stage of imagination, yes." Speaking of Midgard and Middle-earth, he said: "Oh yes, they're the same word. Most people have made this mistake of thinking Middle-earth is a particular kind of earth or is another planet of the science fiction sort but it's just an old fashioned word for this world we live in, as imagined surrounded by the Ocean."
