Either way it still makes the point.
Quite simply mere words have roots all over the place and it's nearly immpossible, especially dealing with dead and practicly dead languages, to find which came first-there's even evidence that the Egyptian (written) language was heavily influenced/based on the Sumerian (written) language when Egyptians started writting. Seeing a Abraham original came from Ur, a Sumerian city state and Hebrew has it's origins in Sumerian...
Language- I think theres too much looking into the origin of this that and the other, too much literalist thinking, too much too much what does this word mean- looking to deeply for the 'letter of the law' rather that the spirit.
While it's all very interesting in the end what does it matter if Amen-Ra predates Amen or visa versa, or if Jesus does or doesn't have a linguistic link to Zeus???????
A dead language once spoken, breathes life again. And with the language, comes the understanding of the one who spoke it.
Egypt follows Hebrew, not the otherway around. Sumarian follows Noahidic, etc.
All follow Adam (as Adam seems to be the similar theme world wide concerning the beginning of man...more or less).
There are exceptions to the rule of course, however they are "young" cultures. The older ones do not appear to dispute the "beginning of man".
