Ultimately it is a question of faith. God may stand right in front of you, but still without your faith, you would not believe it is God. God could perform countless miracles, but without faith, you would be searching for scientific explananations.
So, are you a biological remnant of monkeys, here now, but nonexistent when you die? Without a soul, or a soul without a destination? Or do you believe that you were created with a purpose, that this short life is not a dead-end street?
Its up to you.
