Ilikecheese, has a point. If one can “prove” prophecy, that would be an indication that God exists. That’s why I would catogorize myself as a theist, until such time as I am proven wrong.
For Punky: Seems like Nebuchadnezzar did invade Egypt, but the information is scanty. One thing I know for sure, Egypt was never the same after his invasion. From then on Egypt was a secondary power:
Following the pacification of the Phoenician state of Tyre, Nebuchadnezzar turned again to Egypt. A clay tablet, now in the BritishMuseum, states: "In the 37th year of Nebuchadnezzar, king of the country of Babylon, he went to Mizraim (Egypt) to wage war. Amasis, king of Egypt, collected [his army], and marched and spread abroad." [1]
The following article discusses the next chapter (Is. 30). Scholars split the two, because Nebuchadnezzar would only fulfill Is. 29. Much later Cambyses and Ptolemy Lathyrus would do the rest.
Significantly enough, then, Egypt’s history records the fulfillment of more striking prophecy than does any other nation’s. Their mighty capital, Thebes, has fallen in ruin just as Ezekiel foretold (ch. 30:14–16). By No the Scriptures generally designate the magnificent city of Thebes. “Such vast and surprising remains are still to be seen,” says Pococke, “of such magnificence, and solidity, as may convince any one who beholds them that, without some extraordinary accident, they must have lasted forever; which seems to have been the intention of the founders of them.” However, there are no accidents with God. Thebes sank beneath two of the most terrible blows ever dealt by the hand of man, both of them after the prophecy of downfall. The first destruction came from Cambyses, and the second from Ptolemy Lathyrus. Not until 25 BC was the third part of Ezekiel’s prophecy fulfilled, when the city was finally broken up into separate villages. [2]
