Senusret, I cannot fathom any way for anyone to actually tell you the name of the first Egyptian or any other language which preceeds written history. Sure someone might name it after the name by which they are allegedly supposed to have referred to as themselves, but this gets one back to written times!
So, I contend that "any name" is just that, "any name!" They might well have called it "ma ma!"
