Fly fishing is an ancient form of fishing. It originated to allow fishermen to cast the line further and more precisely by attaching the line to a rod. With fly fishing you are actually casting the line, not the lure. It's the opposite with spin casting.
Thanks--glad you can appreciate what I was saying. I always tell people who have been spin casters and want to learn to fly cast to use their non-dominant hand, as fly casting has a completely different feel, as well.
