Han: "(He laughs at Luke after he is hit by the training unit) Hokey religions and ancient weapons are no match for a good blaster at your side, kid."
Luke: "You don't believe in the Force, do you?"
Han: "Kid, I've flown from one side of this galaxy to the other. I've seen a lot of strange stuff, but I've never seen anything to make me believe there's one all-powerful force controlling everything. There's no mystical energy field that controls my destiny. It's all a lot of simple tricks and nonsense."
