<1. Ok, I will shout it louder (for extra effect I
would go also up the roof of my house, but it is
buried now in snow, and I can not wait)>
This is your first mistake: the snow would have
added the very substance which your arguments lack.
By all means, shout from the roof of your house.
And should you find anywhere evidence for Proto-Semitic,
NW Semitic dialects, rudiments of Arabic - ignore them
completely. After all, Abraham, Moses and David all
spoke Modern Hebrew.
