Which came first to the world of Tyria

Which came first to the world of Tyria, the elder dragons or the human gods (current pantheon or predecessor pantheons)?  Do they have any prior relationship, especially since the human gods created Glint, a dragon, to shepherd their creations?

The Dragons, as we said, have always been here. The gods predate the humans, but not by much. Much of what we know about Glint comes from Glint herself. The truth of the matter may be very different, and she has her own reasons for saying what she has said.
