Lots To Learn

We don't know much on the scale of things. Why do crows crow and nightingales sing? Why do animals have four legs? Human Beings only have two pegs. Why do birds fly and man cannot? These unanswered questions tie my brain in a knot We all have a brain, that's for sure, The brain is our information store. It doesn't matter what we know, Nobody knows much, no matter how far they go. Whatever knowledge education brings, We know nothing on the scale of things.
