Exactly the point of the article. My question is somewhat more pragmatic than the origin of the iron that made up the dagger.
HOw did the ancient Egyptians of the Bronze age recognize a rare meteorite as a metal or having metallic properties and then how did they learn to smelt it into a dagger. This would seem to be beyond the capabilities of the Bronze Age.
They were having problems with folks using iron weapons - Hittites and Assyrians.
