True, but their contribution to peoples existence is a far more better use of human potential.

Either way men and women are superior in their own ways. I don't think anyone can really claim one is superior then the other. They're just superior then the other in different ways. You don't see men hold a child in their womb for give or take nine months, go through childbirth for give or take 30-50 hours, raise, feed, teach their child to walk, talk, live for majority of their child-lives, up into teens and even sometimes into adult hood.
Women naturally are better at maternal instincts, if we had to we would fight to save a child's life, even if it wasn't our child. Does that mean we're not strong because we're not using all our effort to protect, fight etc constantly? Or does it make us more intelligent to not always use it. Men tend to be naturally better at hard-work labour etc, building, construction etc so naturally they go for those type of jobs, which also tends to decrease their life-span.
The male human race are further advanced in life then women have, because history dictates women as home-wives, naturally it lingers on and men are just further advanced then the female counterparts in terms of work. The societies we live in have always allowed men to be further in a lot of fields. Yeah physically majority of men tend to be stronger. Women tend to live longer.
There is loads of ifs and buts and whys and whats, at the end of the day I don't believe either is superior then the other, but in different circumstances they are superior/inferior. There are loads of scientific evidence to prove one or the other, it just is dependent on what you believe is right. Whether it be that women have double XX chromosomes so our bodies are better at fighting off illnesses, or whether men tend to focus more on actually getting somewhere in life in terms of work.
On top of that there is 66M more men in the world so it differentiates the statistics a little.
World population 2016 | World population clock ..contrast that vs different countries. India, they're known for wanting to kill girl babies. China have laws to prevent babies being born (more men in china/india)Western countries have had mainly men go to war/fight in wars (usa/uk/russia have more women). Heritages, cultures, religions, traditions, politics/laws, wars. It's dependent on where anyone lives in the world, the type of countries they live in etc, economic abilities, social constructs, political agendas, west/east etc to really define whether men/women are superior.
