Written language popped up around 5 thousand years ago. https://www.getty.edu/news/where-did-writing-come-from/

Human language was invented ~100 KYA.

50 KYA we were painting pictures of mammoths on cave walls. Before that we were a population of ~200 for many tens of thousands of years in Africa.

Our earliest upright ancestors lived around 3 MYA. https://en.m.wikipedia.org/wiki/Lucy_(Australopithecus)

65 MYA the dinosaurs dominated our world and our ancestors were small rodent like animals.

It’s very hard to imagine that anything we do will stop evolution for hundreds of millions of years in the future.

If 65M years of random DNA mutations caused small rodents to evolve to homo sapiens, what do you think 65M years of human technology can do? Hint: technology progresses a lot faster than natural evolution. Think about how much of an impact evolution had on us in the last 1000 years vs how much technology did. We will probably become capable of editing DNA within a few generations. Death by aging will become a relic of the past. And I'm talking about what will happen within a few generations, not 250M years. In 250M years, DNA-based life will probably be mentioned in museums.
