The first signs of use of iron come from the Sumerians and the Egyptians, where around 4000 BCE, a few items, such as the tips of spears, daggers and ornaments, were being fashioned from iron recovered from meteorites. Ancient Greeks considered Halybes to be "the inventors of iron". The people of the Caucasian Isthmus, Khaldi people (or Khalib/Halyb and Halisones by Strabo) were one of the oldest west-Georgian tribes (4th to 2nd millennia BC).By 2500 BCE to 2000 BCE, increasing numbers of smelted iron objects (distinguishable from meteoric iron by the lack of nickel in the product) appear in Mesopotamia, Anatolia, and Egypt.
