Same myths all over the world?

Well yea I agree with that, but what you should be looking into are humans. All these fabulous stories, myths, legends etc are created by people and I think that are more similar than other think. They always say that each person is unique both physically (ADN) and psychologically, but I think that in a general way we are very much alike, the way we create, paint, write, sing, work, think, have desire, greed, ambition etc etc...
