Pre-iron age people were sometimes aware of iron. Meteorite iron was not unknown to many cultures. The likelihood that Noah would go around collecting meteorites to put his ship together seems kind of remote, though.
The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia and the Stone Age in Africa, with exceptions. Meteoric iron has been used by humans since at least 3200 BC. Ancient iron production did not become widespread until the development of the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy. The start of the Iron Age proper is considered by many to fall between around 1200 BC and 600 BC, depending on the region.

Iron is so inferior to bronze as a metal that even after smelting was discovered, some cultures, like the Etruscans, preferred to sell the iron they smelted to others, and to use bronze for their tools and weapons.
Iron is cheap and readily available in most places, while copper is not.
