What if there had never been any men on planet Earth?

What a miserable place society would have been without good old men. We may be able to exist without them in a fantasy world, but definitely not in reality. Just like women, men has flaws and weaknesess, but their good overshadow the bad. I do not think they are a better specie than what we are, because I think that we cando most of the things that they do, some even better.
