Iron is not natural to the Earth

 IRON

 Iron is not natural to the Earth. It did not form on the Earth but came down to Earth from outer space. This may sound strange but it's true. 

Scientists have found that billions of years ago the Earth was struck by meteorites. These meteorites were carrying iron from distant stars which had exploded. 

The Quran says the following on the origin of iron, WE SENT DOWN IRON WITH ITS GREAT INHERENT STRENGTH AND ITS MANY BENEFITS FOR HUMANKIND (57:25] 

God uses the words 'sent down' for iron. It is clear from the verse that iron is not an Earthly material, but was sent down for the benefit of humanity. The fact that iron came down to Earth from outer space is something which could not be known by the primitive science of the 7th century.
