Different between swing and knitting

What is the Difference between Sewing and Knitting? When sewing you are piercing a pre-made fabric with a sharp needle to join them together by a thread. When knitting you are not using sharp needles, you are using larger thicker ones. When knitting you are creating fabric by making stitches with yarn.
