Things we have to know !

We know almost nothing from the world.Why is that? How's that possible ? But do we know our self ? There is a magician link with human kind and world existence.We say or we have heard that human kind has been evolving but did the world also evolve too ? Of course ! The world is changing we are changing too .So what's the point? The point is that we focused mostly in our appearance evolution not in our brain evolution.We know almost nothing about brain activity so we try to know about the world and space.The think we have to know is that the secrets of space are not bigger than brain's one , so we have to be awareness that the big discoveries comes only when we discover something new from our brain !?
