“I think saying Chaza’l were wrong about science is simplistic and wrong. “
It is simplistic. I take issue with the word “wrong” though. It is clear that we have a better understanding of HaShem’s creation than anyone did at the time of Chazal. Chazal consistently used the best non-Jewish methodologies available at the time and it is entirely inappropriate to criticize them for that. Were they living in our times they would use the best methodologies available today and would reach appropriate conclusions. Nevertheless it is also inappropriate to treat the talmud as a science text, and indeed that has been asur for a thousand years regarding medical science.
