@UJM Then we may not be arguing, just talking past each other. The point I was trying to make is that it isn’t correct to fault Chazal for not knowing about electricity, vaccinology, anatomy, anything really the way that we know today. They didn’t know about those things, because their scientific knowledge was limited to what the secular world knew at that time. Whether they got it from studying the Torah or from going to Greek medical school is a different item entirely.
What @kuvult said above is correct. It is not a pgam in Chazal that they did not know everything about science. It doesn’t take away from their gadlus in Torah and kedusha AN IOTA. Some of us have been taught that Chazal knew EVERYTHING, and that’s a bad thing to be told, because the reality is that they didn’t. And if you tell someone like the OP “Actually Chazal were right about lice” or “You could be matir a woman if her breath doesn’t smell like wine, that’s how the body worked in those times” You’re setting them up for failure
