Fe is beyond miracle. It is mercy from the Creator.
Gravity was created in the process of creating the universe
By default of natural rotation. The Universe will be ended or stop rotation before this...in other words gravity has gone before as mentioned in many books.
But why we still have that? It is because of His mercy by sending down the Iron and keep the ends under His will.
As geologists have confirmed that Iron was not formed during the cooling of the Earth.
