Because the world thinks this refers to literal Isreal and it doesn't. And you're exactly right, if it did, it would be false for the very reasons you mentioned, and many more. The Jews and Earthly Isreal have long not been God's people. Even Jesus, said so.
While prophecy at times takes on a metaphoric view, that really should not invalidate it if it adds up. To take that stance you have is to in a way lack reason. There are plenty of metaphors in your life maybe even your parents have used to explain things to you that once understood made sense. So why cannot the Bible do the same at times?
Like I said before...I even broke this down logically for you as to why
I'll restate this again...(briefly)
All other accounts, facts, stories are things people are capable of creating. The two types of information that only a god could have revealed are:
1. Specific detail information about prehistoric earth and life that is now confirmed by geology and paleontology. If the original scriptures had this Information, then that would be strong evidence that it came from an all-knowing creator that knew prehistoric conditions.
2. Accurate detailed prophecies about current, or historical events that are well documented. If these predictions were in original scripture versions, they would be evidence that a god revealed them to the authors. Specific dates, places, and names are the necessary detail.
D. The claims of prophecies and scientific facts revealed in scripture do not have enough specific detail to allow verification, and creative interpretation is necessary to match them with any current event or knowledge. An account of prophecy fulfillment written after the event occurred is not a prophecy. Stories of miracles are not evidence of divine revelation because these accounts can be created by people, and cannot be verified.
E. Without adequate evidence of god contribution, a book of scripture and the god it represents are only inventions of the human imagination. Belief that a god must exist, does not imply that any particular book of scripture has a god as its source. The scripture itself must contain clear evidence that it is the revelation of a god.
F. For a Christian or Muslim, arguments about god as the first cause, order and complexity, the source of morality, Pascals Wager, etc. are only interesting intellectual exercises, because the god these arguments propose is a generic hypothetical god that is not connected to any specific book of scripture.
Now as to your 2nd paragraph;
We are not talking about moral lessons. WE ARE TALKING ABOUT PROPHECY BEING ACCURATE. And it's not. Either something contains detailed factual information, or it ****ing does not. END OF STORY. GAME OVER. You are not saying the BIBLE in this context is trying to explain something that is conceptual...you are saying these prophecies have been accurately recorded, stated, and verified from biblical testimony that DIRECTLY AND ACCURATELY correlates with today's and the events of modern time.
The bible gets no special pass. If I told my nephew for example that...in 20 years...(you will marry a girl with a vowel in her first name)...first off, that's not a prophecy. It's an educated guess at the very best. Why? Because most females do have first names with vowels in them. If I told him that he is going to marry a girl and her first name shall be Janice. Well she's got 3 vowels...just as well it could've been Amy, Sarah, Connie, Kimberly, Stacy, Yalonda,etc...etc...NOT VERY ****ING SPECIFIC.
If I were to tell him rather...you will marry...Michelle Stevenson from Oakland, CA...whom used to live in Lombard St...Apt 1245..from 1989-2004...and you will be uncle to her two nephews Jordan Tamir..and Chris Blake.
Details are what separate prophecy from a well educated guess.
I'm sure someone who might've been around at that time and saw the destruction of that Israel...might've just figured that..."it ain't over" and "they'll be back". Perhaps as the Jews left...he heard someone remark that they shall re-claim what is rightfully theirs. Many nations, and empires..constantly re-claim what was once lost to them in battle. The logic being Israel would be no different.
So there is you reason for suggesting why someone would think like this..at that time.
A human creation and a logical thought of people getting back lost/stolen property. A very human concept. And besides if this GOD that you claim exists, and Muslims know they were going to get this back....then why take it from them in the first place?
The sad irony to all this bullshit is that..GOD apparently told the Muslims something else..or rather cut them another deal. Which further proves either GOD exists and is a ****ing liar. Or rather human beings decided they wanted that land...didn't like what they read from another's holy book..and needed a justification for taking it...
GOD tends to back up any kind of claim one can make, funny how he's never gotten off his cosmic ass in the last few hundred years to address..the children he loves so much not only from killing eachother..but also other people. No, no, he would rather much sit on his ass and do absolutely nothing. And this is the GOD you folks claims loves you, but on top of them is deserving to be submitted too...
Religious people simply are in love with an abusive partner, and make excuses just like a battered partner..to their behavior.
