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?
well they're basically just people like us who rely in studies and facts and obviously not all things have been studied and have been given factual proofs yet. that's why these scientists and others like then are continuing to make researches to come up with answers for people like you with questions.
