Were Humans Created by Reptilians?

I think the Bible has as much authority on this as Tolkien:

"Far, far below the deepest delving of the Dwarves, the world is gnawed by nameless things. Even Sauron knows them not. They are older than he. Now I have walked there, but I will bring no report to darken the light of day." - LoTR

"Some of these caves, too, go back in their beginnings to ages before the goblins, who only widened them and joined them up with passages, and the original owners are still in odd corners, slinking and nosing about." - The Hobbit
