Metallatry

Metallolatry is the worship of metals. Why metals are smooth, strong, shiny, and unique generally disagree between science and religious thinkers. God make metals in the earth for mankind to use so they can make advance tools and allow their civilizations to advance to where we are today. If metals don't exist, humans would've still been hunters and gatherers right now. Less importantly due to its shininess, metals would be used to decorate for beauty. The shininess would increase the feeling of love, that's how men traditionally give women a wedding ring in order to strengthen the bond more drastically.

Metals don't last forever. Metals turn to rust after some time. Rusting is the act of God of turning metal into a non-metallic substance.
