Obviously it's possible; smartphones exist. Perhaps you think the necessary technology was given to us by aliens?

You are going to need alot more than iron.
Copper, gold, lithium , aluminum, oil (for plastics), not to mention all the exotic chemicals found in the fabrication process. You need to be able to find these materials, they aren't scattered around on the surface you will have to dig.
