You’re taking a radically different past, and then somehow arriving at the conclusion that any part of history that we current know would have still happened.
No, I’m assuming we had an advanced civilization 10,000 years ago then assuming continuous progress was made.
I threw out the Great Plague, or something similar, as an example of something that wouldn’t have occurred because science would have addressed these types of diseases. Covid today would be easily treatable in a more advanced society
Clearly history wouldn’t play out the same way. The point is that today’s society would be much more advanced
