Question is pretty simple. We know for a fact that somehow, we owe a lot to the ancient civilizations for our current way of life --- one way or the other. I was just wondering who among these great civilizations(ex. Sumerian, Babylonian, Chaldean...NOT LIMITED TO THE CIVILIZATIONS FROM THE FERTILE CRESCENT) deserve the greatest praise in terms of economics, laws, customs, etc... Feel free to post your thoughts.
