I post in the voice of Christopher Walken
I am not a deep Tolkien fan (I have only read the trilogy a handful of times and the hobbit a couple of times). But I always assumed he was doing the same sort of thing that Howard was doing, which was shifting things far enough back in time that he didn't really have to worry about real history (anything that is out of place can just be explained as forgotten to time). Though I will say the Lord of the Rings seems a lot less kitchen sink than Conan
