Iron is a metal that is essential for human civilization but is not naturally occurring on Earth. The Quran correctly stated over 1400 years ago that iron came from outer space. Scientists have since discovered that billions of years ago, meteoroids containing iron hit Earth. Additionally, only massive ancient stars could generate enough heat to produce iron, which was then dispersed throughout the solar system during supernova explosions. The Quran's mention of iron originating from space predates this scientific discovery.
