Well, no, you're almost right. The Hebrew Bible in the Hebrew language mentions Arabs (aleph, resh, beth) which derives from a root word that means, ironically enough, "Ambush" or to lurk, lie in wait. The first instance is Joshua 15:52. Both Ishmael and Israel descend from the same father, different mothers, they are half brothers. Both sides of the question readily agree to this! It's a family feud. One of Israel's 13 or so children was named Judah. Judah's tribe united with the tribe of Benjamin and they became the southern kingdom, under the reigns of David and Solomon. The hot bone of contention was where was the correct place to worship God. Bethel (the House of God ) in the north had the earlier claim. The Judeans and Benjaminites claimed revelation and establisjhed a temple in Jerusalem. The ten tribes to the north rebelled after the death of Solomon and the miserable reign of his son Rehoboam and it remmaind that way until the Disapora. It is interesting to have this in mind when you read the account of Christ and the woman at the well in Samaria. The Jews as a state and a religion hated the Samarian even to the time of Christ even though they were all closely related as were the Arabs. As a religion, the Jews (as descendants of Judah and Benjamin) they believed they were the guardians of the TRUTH. If one consented to this and converted he too could become a Jew, of sorts (the religion aspect) but he wasn't as Jewish as one born a Jew. In this day and age that has sort of lost it's distinction among many, although many others claim to have kept their genealogies from ancient times. So, Judaism is a race and a religion neither of which are absolutely necessarily inclusive. You can be of the Jewish (and in the broader sense "Semitic") race and not be a religious person. Such is the view Hitler took. You can be a Jew and not be Semitic like Sammy Davis Jr. was. Pretty much the same with most of Islam and being an Arab.

As for Noah, he was neither. I don't think he took any termites along for the voyage (for obvious reasons) and yet here they are. I know of certain fundamentalist who even claim that he had dinosaurs on the ark because since the Earth is only 6000 years old they had to co-exist with man AFTER the Flood. Since God is not the author of confusion, I tend to not buy this reading of events. Thinking like this happens when you believe in Holy Ink. In those days the "whole earth" was a much more local event especially since, as you pointed out foolestroupe, the extent of the Earth was so largely unknown. Big flood to them! It got everything, i.e. the "Whole Earth" and what foresight to save your farm animals and sacrificial animals. If God in His wisdom invented nature and the laws of nature I would have to assume that all He did, He did through those laws of nature. Some very extraordinary events DO take place in this world, some quite devastating and if you believe in the Creator you may understand these events as having purpose but the "natural" explanation will also hold water (pun intended). This always brings the question of God down to a matter of faith as opposed to a provable fact. I've got some Scripture for that too but I'm sure you grasp the concept without going into detail.
