I don't even fully understand the OP, perhaps that's why you're not getting a logical answer.

Or, more likely, you're asking questions that cannot be answered because they're based on historical evidence. If I'm understanding you correctly, you're asking how the Qu'ran could have predicted that the Dead Sea was the lowest land on Earth even though there was no way of knowing that was true? Well, there's your answer. A combination of knowledge that the Dead Sea was low lying, guesswork and presumption. I don't even know if the Dead Sea IS the lowest lying land in the world, I don't know very much about the Qu'ran and I don't know what specifically you're looking to get out of this thread?
