Middle Earth - Unstuck in Time?

[Imladris]

To say that Middle Earth came at a time prior to that is erroneous because we are talking about two separate and totally disconnected worlds.

Tolkien wrote LotR as a mythology for England (letter 130). Also Letter 156:

But they were still living on the borders of myth -- or rather this tory exhibits 'myth' passing into History or the Dominion of Men

Myth

And, I never said not to be descriptive. I write like I explained in detail in my former post (I suppose this makes me lazy, I don't know). I said to draw on the information that Tolkien based his races on.

I, however, do not feel it right to tamper with Tolkien's myth if he has left such things vague and if there is no cultural basis to turn to. If that is lazy then I am lazy.
