Many Science-Fiction stories have what are called "Fix Points in Time". Theseare events that are supposed to be so important to the future that nothing can change them. One of these in many stories is the John F. Kennedy assassination. The way the Fix Point in Time theory goes I could go back in time whenOswald was 8 years old, kidnap and kill him. Still on November 23, 1963 in Dallas TX. at the Dealey Plaza at 12:30 CST Kennedy will be shot and killed. If before they started the drive I had put ahole in the tired for some reason the air would not have leaked out. Would it not be so that if there are fix points in time and no matter what is done the event will still happen as planned be proof that there is a God? Someone has to be not only in control but have so much power over events that nothing stops the event. All things are done according to God's plan and not even time travelers ot Time Lords can stop them.
