Here is Grok’s conclusion…
“The Hittites in Deuteronomy 7:1 are likely a localized Canaanite group, possibly with cultural or ethnic ties to the Anatolian Hittites of Uşaklı Höyük, but not identical to them. The biblical Hittites were part of the Canaanite nations targeted for removal due to their idolatrous practices, as per the divine command to prevent cultural corruption. The Hittites of Uşaklı Höyük, as described in the article, represent the imperial Hittite civilization, whose influence reached Canaan but whose core was in Anatolia. While not the exact same group, the Canaanite Hittites in Deuteronomy may reflect a southern extension of this broader Hittite cultural sphere, as archaeological evidence suggests Hittite presence in Canaan during the relevant period.
“Ongoing DNA and paleobotanical studies at Uşaklı Höyük, as mentioned in the article, may further clarify the relationship between these populations, potentially revealing whether the Hittites in Canaan shared genetic or cultural markers with their Anatolian counterparts. For now, the connection is plausible but not definitive, as the biblical term likely applies to a localized subgroup within the broader Hittite cultural framework.
Since it’s just a fact that the name “Hittites” was borrowed from the OT to refer to a previously unknown and unrelated group hundreds of miles to the north, Grok and you should get a new hobby.
