Answer:
I drift forever with the current and flows to your everyday life. I make living easy but I am good at killing people too.
I come off of a beautiful creature which soars in the sky. I come off of a peckish creature which has a tail as mighty as the sun! I am sometimes dirty and parents beg you not to pick me up.
I can generate fear and some say I come out of your ears. I am as quiet as a mouse but not welcomed in the house.
You can catch me but cannot throw me. What am I?
I'm as simple as a circle worthless as a leader; but when I follow a group their strength increases tenfold. By myself I'm practically nothing.
you hold my tail while I fish for you
