Gender issue

In ancient times, while humans were living in caves, they needed food. They weren't aware of agriculture yet, the only food were the animals. So, they had to hunt them. But how? They invented spears, arrows and bows. They had to run fast, they had to be strong, they had to be tough. So, they decided that the men should be doing the hunting. And sooo the story began and evolved to present. Now, as we all saw, men are causing almost all violation, crime and most other things we saw. And women are being sexualised, treated as objects. Now i wonder, what if at that ancient times the desicion was opposite. What if from that time, the women would do all the hunting, working, what if all soldiers were women? Would the men be treated as objects? Sexualised today? Or at some point would it turn this way again the way it is today and how? i really would like to being able answering this question but it's obvious that it's hard to imagine a whole different world. i think the question will remain forever, or, can it turn at some point the opposite in the future..
