The Hittities were the first civilization to make weapons
out of what?

Iron Weapons.

Explanation:

The Hittite empire, first to smelt iron for tools and artifacts, emerged as a civilization and formidable military power around 1600 B.C. before eventually being weakened and defeated around 1200 B.C.

The Hittites were an Anatolian individual who assumed a significant part in setting up a domain focused on Hausa in north-focal Anatolia around 1680-1650 BCE. This domain arrived at its tallness during the mid-fourteenth century BC under Šuppiluliuma I, when it enveloped a territory that included a large portion of Anatolia just as parts of the northern Levant and Upper Mesopotamia.
