I was just wondering they say that science are perfect. How come that they cant give a pure answers to some issues to like why do people dream? They say that it is on the psychological effect but it is not certain
Why is that there are left handed persons? Any thoughts about this?
First and foremost, science is not perfect. And scientist are still researching so as to better understand some things in the world.
They are not God to know everything in this universe.
