It is just like with the Bible, Josephus, et cetera:
Do not trust the people who lived then, or shortly thereafter; oh no, only trust academics two thousand - or more - years removed.
It was once fashionable to categorically denounce the historicity of the Bible because the Hittite Empire was clearly mythical.
Then they found Hattushah, its capital... so they just moved on to the Next Big Reason to denounce the historicity of the Bible.
Academics are typically disingenuous anti-Christian snobs.
There are many archeological discoveries that support the Bible. And none that refute it. There are undiscovered things, but, as you said, when artifacts or cities are unearthed, they support the text of the Bible. One day, Noah’s ark will be located and then real fireworks will happen.
That's not what happened.
When Hattusas was discovered, the Old Testament "Hittite" name was used to label its empire.
