As far as I can discern these days no one in the general population has any thoughts of Sumer, Babylonia, Assyria, Ur.  For the American young the 1940s, not 2,500 BC, is the ancient past.

A time so long ago that it predates the Old Testament by 2,000 years is probably imagined as a brutal and politically incorrect time of inhumanity and human sacrifice.  In short, a script for a horror fantasy movie or a video game.

In actual fact, these civilizations were more advanced and more humanitarian than our own. They were more advanced because the rulers were focused on ensuring the society's longevity by maintaining a livable balance between debtors and creditors. It has all been downhill ever since.
