The person you were replying to was asking about cities. The article you are posting is about Sedentism - "the practice of living in one place for a long time". The figure of 25,000 years ago is for the first evidence of permanent settlements. These do not fit anyone's definition of a city.
The first evidence of cities are from Sumer, which is what this whole thread is about.
The person I replied to replied to me. I never mentioned city, but they injected the word city nonetheless probably because they had no idea what they were replying to or what the words meant. What qualifies whether any fixed permanent or semi-permanent settlement is actually a city, town, hamlet, or village is entirely subjective.
You referred in your above post to colonies/cities that were over 45,000 years old. Although I don't doubt such a thing is possible (maybe just lost to history), my last dive into this had scholars claiming the oldest known cities to be in the range of 9,000-11,000 years old like Gobekli Tepe and its sister cities. I was just asking if that consensus still holds. I can see this is getting into semantics a bit though and what the definition of city is.
Yes you did:
> first settled into fixed colonies/cities around 45,000 years ago
nope

Yes, the dividing lines are blurry.
No, it is not totally subjective
