That’s actually one of the few worthwhile “twists” from either the book or the movie in my opinion. I like the idea of a past “earth” in the sense of our modern one being so thoroughly beaten and destroyed that it is no longer recognizable. Taking a “primitive” human and showing them how great humanity once was is one of the cooler ways to reflect on the work of mankind, imo.
