There is no outright proof that God exists. Neither is there outright proof that evolution is fact and thats how we got here. Even if you could see it with your own eyes you wouldn't necessarily believe it. This very thing happened when Jesus performed some miraclous signs. But they still didn't believe. There is substantial evidence that the bible is true. The historical account of the bible is well supported even outside the bible text. There have been archealogical sites that have uncovered items that support the historical account of the bible including the dates and so forth. All this doesn't prove God, but it does support whats written in the bible.
