Israel was NOT arbitrarily created out of other people's land - Israel's land was returned to its original owners ..... there really can be no debate that the Jewish people were the initial owners and that they have had possession of that land off and on throughout history .....The region was initially called Judea and inhabited by the Jews until the Romans conquered and renamed it Palestine. Later the Arabs conquered it and had primary possession for the next 1000 or so years.
Hard to separate out the bits I want to comment on! I have two points. The first is that the region was NOT initially called Judea and inhabited by Jews - I'm not quite sure when Judeasm started, but it was certainly well post Abraham. Prior to that time, whenever it was, the area had no association with Jews because there were no such people. I don't know when they first settled that area of land, but whenever it was it's irrelevant. It doesn't make it "theirs". Judeasm didn't start there - it started (AFAIK) either in Mesopotamia or near it.
The second is that if you study the movement of peoples over the past few thousand years (being increasingly understood, especially with the modern tool of mitochondrial DNA) you'll see that no region has been populated for long by what can be seen as a single homogeneous people. Go back even further and all the areas we are talking about, plus Europe, India, China, had yet to be populated by humans. This is all in the era of modern humans - I'm not going back to pre-humans. We really haven't been around all that long.
If it weren't for the myth (using that word in its strict sense, non-pejoratively) of what has become known to Christians as the Bible there would be no "history" of Jews in that region, nor in fact would there be such an identified grouping as "Jews". The whole thing is a tribal association. Just because they wrote down that they considered a particular region to be inalienably theirs doesn't make it so.
Even a quick look at the populations occupying northern Europe and the British Isles shows that there is no such thing as "British", "English", "Scottish" or "Irish". Each modern grouping, purely geographical and in no way ethnic, has pushed out and/or intermingled with other groups before it. Purely tribal, before the days that land was considered "owned" by anyone. In Britain, for example, there was no concept of land ownership (as opposed to current occupation) until the Normans arrived and set up the system because it was advantageous to them. If we were to decide to reinstate Britain (say) to it's "original" condition and restore its "original" and "rightful" inhabitants, just who would they be?
Your argument is the nub of the Jewish case for taking and keeping that land with no concern for anyone else and is behind the incredibly racist regime in Israel. Although Muslims have other reasons for rejecting Jewish claims and I don't subscribe to those reasons, I do support their claims as all the facts point that way.
For some months back at university I had a girl friend who was Jewish. I still have several friends from those days who are also Jewish, and indeed I have Jewish relatives. This girl and I fell out when she said something that I queried, to the effect that she was one of the chosen people and that I could never aspire to her level because I wasn't. We discussed this for a while and I left the relationship. How can you relate to anyone who says to your face that they are intrinsically better than you? In my observation this attitude is behind the modern country of Israel, and I fear that country is doomed to conflict until they realise that they're just humans, like the rest of us.
