Really? The Hebrew language is nearly Arabic? Did it occur to you that Hebrew was spoken and written thousands of years before Arabic? Many languages in the Middle East share common words, however Farsi is nothing like Arabic, neither is Kurdish, Turkish or Pashtoon. That's like saying Spanish and English are the same.
It's not an argument to claim that Hebrew is older than Arabic. Arabic developed from Hebrew. Arabic and Hebrew are more similar than Spanish and English (mainly because of the Germanic influence on English).
First when you get past telling us how in the world native Americans could possibly communicate in Arabic with Columbus, you can then admit that you make wild unsubstantiated guesses. In fact Arabic was the language spoken on the Arabian peninsula which had very little contact with Hebrew, it is also the lnguge the Koran is written in, and exported to neighboring countries from Arabia. If you are remotely familiar with Arabic and Hebrew you wouldn't claim that they are "closer than English and Spanish", whichis a ludicrousif not ig orant claim. The languages affected by Arabic are quite simply places where Arabs invaded and occupied the longest, to spread their empire and religion. Which brings us to Arab / Islamic imperialism and nationalism through invasions, murder, theft, and ethnic cleansing, But that is a different thread and subject matter for another day.
