do you have. Not opinions. Some say 600, some say 400, some say 200. All I know is the things that were said to have happened, happened. Cant argue whether that's fact or not.
Plus, when you put into perspective the many other prophecies of the bible that came true, one disputing it would have to take the it was written afterwards stance. Because they have no other argument against it. There are many disputes on the subject of evolution.. even with the very ones who try to prove it happened.
