My explanation: I thought e was incorrect because Sumer, Akkadia, Assyria, Babylon and Persia were geographically dispersed (or so I thought I never checked) and they could not have similarity in the script. Also, I *know* that Persian has a script like Urdu and Arabic and I *thought* Sumerian script must be some thing cuneiform like the Mesopotamian script - so no similarity. I liked the daffy because I like scripts. I know... a lot of incorrect thinking and no LingIU - but then you are not supposed to LIU.
