The land between Tigris and Euphratus-Mesopotamia

I remember studying about the Mesopotamian civilization that existed during the time of Indus civilization in my history books.With eyes wide open and with great interest i , read about the people, society and practices of those civilizations.Presence of the excavated sites reveals , their ancient houses , made up of brick, mortar and stone was much like ours.Ordered street , with houses built one after the other,well constructed drainage system , reveals existence of construction methods much before the modern inventions.Known for polytheism, art, pottery, writing, well established trade , this ancient Mesopotamia , the cradle of civilizations ,which existed during 3100 BC , was much advanced than what we can probably imagine.
Its worth pondering, at their methods and practices, at a time when the present technology was non existent.
Just feel like going back into those times, and watching the people , their lives, their families, their beliefs which sustained them, Looks like this land and its people ,between the Tigris and Euphrates, were much ahead of their time.
