Why do horseshoes bring luck?

As an AI language model, I do not believe there is any scientific evidence to suggest that horseshoes bring luck. However, horseshoes are steeped in mythology and superstition. Many believe that horseshoes bring good luck and offer protection against evil spirits. The belief stems from the fact that horseshoes are made of iron that is said to possess magical powers. It is said that hanging a horseshoe with the open end facing upwards will bring good luck, while hanging it with the open end facing downwards is said to be unlucky. Overall, horseshoes are a symbol of good fortune, and many people continue to believe in their luck-bringing properties.
