If you are interested in the far past, you might consider taking look at an interactive timeline of ancient history I created using data from Wikipedia:

Mehrgarh [1] one of the oldest city in South Asia (pre 7000 BCE) is missing.
Thinking about this stuff stirs the same childlike wonder I used to have as a kindergartener thinking about dinosaurs and trying to comprehend or imagine what life must have been like so many millions of years ago. I very selfishly hope (but have no proof) that we will find earlier and earlier evidence of proto-writing. What a grand mystery and story!

Perhaps an unconscious bias of literate cultures. In the Canadian high arctic years ago, scientists discovered evidence of "paleo-eskimo" (bad name) peoples in the soil. These included more primitive hunting tools than were used by the Inuit people who were there when Europeans arrived.
They took to the tools to the village elders excited to show what they had found. The news story reported that the elders said (paraphrase) "Yes we know. These are the Tuliit people. We have songs about them" :-0
It seems like a quite conscious decision. That's how categorizing things works. You have to have a definition, however vague and exception ridden, otherwise your words don't refer to anything.
More generally, history (as a field) deals with those records, where archaeology as a field deals with the artifacts. They obviously interact and inform each other to varying extents, but are distinct in their practices and habits.
I've worked on both sides of the "writing line" and frankly, the process is very much the same in most cases.
It seems to me using the current names of places for finds is pretty standard, and gives a modern audience a decent chance of understanding it. Is the a particular reason you object to it in this specific case?
e.g. To use an example local to me - plenty people would talk about "The Romans in Scotland" even though there is no historical overlap between the two.
Last changes that I could think of are the occupation of Crimea in 2014 and the split-off of South Sudan in 2011.
