These arguments are very well, but to point to fulfilled prophecies would be also a possibility to prove God's existence (The Bible mentioned in "Isiah 17:1-2" thousands years ago what's going on in Syria these days), not to forget prophecies which to come true at the moment and show all of us it can't be a coincidence the Holy Scripture knew it a long time before all these things happened!

EXAMPLES

NWO (New World Order) = Globalization = Revelation 13:7
One faith for all (against 2. Corinthians 6:14-15) = Ecumenism = Revelation 13:8
One Currency for all = Cashless Economy (RFID-Chip) = Revelation 13:16-17
