It was once thought that the Hittites were only mythical stories in the Bible. But again, the Bible was correct and the Hittites were a major civilization rivaling the Egyptians and Mesopotamians. They were just so utterly destroyed that no other records at all remained of them.
That’s not what happened at all. The name Hittite was taken from the Bible and turned out to be utterly unrelated to this so-called “forgotten empire”.
Not so utterly destroyed, more forgotten.
Also, Hittite is an exonym - they called themselves Nešili or Nesians because they were the descendants of the people from Neša, which is the birth city of the Hittite dynastic culture. Otherwise they were called Hatti, which was mostly used by foreigners and refers to the people from Hattusa
Took around 3,000 years to find the great Hittite empire. Wonder what other histories are buried....never to be found.
