Why is it so hard to fig. her out?

I’m a pretty ytical dude, I consider it a felt myself. Anyway I have a question why is it that humanity has two genders, we are both almost identical in every way other the ovious.wev been on the planet for the same amount of time, but when it comes to what she’s thinking or what she wants 99% of the time men have it dead wrong? You would thing a space that has triumphed over every other none living organism on the planet wouldn’t have trouble with “should I call her?”
