Think about my posts above Sunny23. What does the physical evidence of history and your own eyes tell you about whether there is an intervening God or not?
Once you've followed the evidence to it's inevitable conclusion, all you really have left is Pascals Wager. One chooses to believe in God not for evidentiary or scientific reasons, but as a sort of insurance policy just in case.
Pascal's Wager is an argument in apologetic philosophy which was devised by the seventeenth-century French philosopher, mathematician, and physicist Blaise Pascal (1623–1662). It posits that humans all bet with their lives either that God exists or does not exist. Given the possibility that God actually does exist and assuming the infinite gain or loss associated with belief in God or with unbelief, a rational person should live as though God exists and seek to believe in God. If God does not actually exist, such a person will have only a finite loss (some pleasures, luxury, etc.).
