pretty much every study of these sort of things show that there is very little difference in performance between women and men - maybe on the scale of 5%. There is more difference between members of the group than there is between the genders. so it didn’t really make much difference when it came to deciding who should do what.
ultimately, it doesn’t matter, the difference is so slight that it was basically not noticeable, if it even did exist.
all modern anthropological research demonstrates that women and men pretty much did an equal share of all tasks, including hunting and raising children. if your masculinity can’t handle that fact then I’d recommend therapy.
Actually, the history of why women divisions arose in sports is far more nuanced than you seem to believe. The main reasons for doing so were primarily rooted in sexism. Historical records show that women were able to compete with, and win against, men in sporting events during the early middle ages.
Anyways, I see there’s no reasoning with you, so I hope you have a pleasant evening
