How many wars were led in the name of God?
How many persons were killed in the name of God?
How many lost their faith in God because of those pretending to be the men of God?
@Viewfinder: "... excuse for their own absent faith in God"? Do I need an excuse for my absent faith in Zeus and fairies as well? A more valid question to add would be "How many lost their faith in God because there is no evidence for such a being and because the world and the universe can be studied and explained without having to invoke the concept of god(s)?"
@Viewfinder: Your question makes sence for me in a lot cases, but not in all of them. @Aaron Schmidt: For me personally as someone who believes in god, I have more evidence of God in very simple stuff and more in my heart more than anywhere else. I can say also that God is not a being that we have to believe in or invoke, but more a being we need to believe in.
