“Except Israel does have defined borders in the Bible.”
I suppose you could try that argument, except that the current “nation of Israel” doesn’t match those borders. So if you use that standard, the nation mentioned in the Bible still doesn’t exist in the current day.
So I’d say that’s probably not the best standard.
No it doesn’t perfectly match the boundaries but it is still there. And it is the only nation with defined borders in the Bible IIRC.
