Iron use does go back to 4000B.C. It was largely because of meteroric
iron. The ability to smelt iron from ore only happened much later.
We know this because the _furnaces_ themselves _don't_ rust and _aren't_
recycled. These furnaces are rather specialized because of the high
temperatures required. We see no evidence of them anywhere near
4000 B.C.

Which makes me wonder how people ever came up with the
idea of smelting iron. Why ever think of making higher
temperature furnaces?
