Dude, for your question.......................first of all ask urself..........egg came first or hen.............................then question about existence of men and women.........it is demand of nature.......................and there would have never such a huge popultion in earth...............or are trying to think that we will come out like in matrix movie........................It is great to have diff gender availabe in this universe coz it makes this homosapiens going............we are lucky not extint yet............ If u look at the hinud mythology it says first manking was manu....................and he was given a company by god taking his one ribs............he created women......coz manu asked god...........why all the animals have couples why i am alone......... the other thing is why we have diiff nature coz of evolution................we men started going for hunting and women started picking the food........taking care of rest of things in cave................our mentality grow superiour coz we were providing food....... do u know why women talk a lot...........coz when they start to pluck the fruits and gather the woods for fire.........they started talking to each other.........so they became talkative coz they have nothing to do but talk while plucking the fruit.......men became hunters so we had to be silence and get the target.....................average women speaks 6000 word a day and men 2000 word a day................ aru kura lord pashupatinath lai sodnu
