In the published version of J.R.R. Tolkien's Silmarillion, the sun and moon don't exist until they're born from the fruit of the Two Trees of Valinor, by which time Arda has already been existence a considerable while, and the world starts off as flat, changing to a globed planet after the fall of Numenor. This is what most Tolkien/LotR fans are familiar with.
What the majority of people probably don't know is that, towards the end of his life, Tolkien was working on ideas for the book which were quite different from what was eventually published posthumously. The book Morgoth's Ring (One of the History of Middle-Earth series) contains an essay by Tolkien entitled "Myths Transformed." Here he largely does away with the notions of Arda ever being flat and the sun and moon coming from the Trees; instead the world is round from its very beginning, and the sun already exists when it is made. But Melkor attacks the sun, thereby "polluting" it and/or shutting out its light. Some of the sun's untainted light is then contained within the seeds of the Two Trees, which return to it with the Trees' deaths.
Personally, I think it's a shame this was never properly published, as it sounds very interesting, and it's intriguing to know that Tolkien was attempting to reconcile his mythical prehistory with real world prehistory to some degree. What are other people's opinions on the matter?
