I've read the Silmarillion which talks about the coming of elves, men and dwarves. We know that Aule made the dwarves and Eru made elves and men. But who made the Hobbits? There isn't any mention of this in the Silmarillion anywhere. You would think important characters Bilbo and Frodo being the protagonist in a book would mention where their specifies came from. Was this an oversight by Tolkien?
