Hey.
I'm the odd one out that has never been raised to believe in entities, never experienced an entity even as a Catholic, and never pondered the meaning of life and anything like that. Had more important matters on my mind.
God is a collective term for people's experiences (mysterical, literal, or not), feelings, thoughts, and wholeness in being (the "awakeness" feeling) they get. It's the blessings (or events that happen towards their favor) they attribute to an outside source. Everything that is about god whether written or testimony is from someone's or a community's experience.
These experiences, testimonies, and so forth can be proven (aka: god can be proven).
As an entity, as many non-christians (and many atheists on RF portray him) he does not exist. If he does or you have an idea that he does, I'll ask the same question of atheists as I ask of theists (specifically christians since other believers "get it"). What is a god to where you can quote there is no evidence for? What are the characteristics of this god so I can determine, test, and make a conclusion on whether or not evidence has any meaning in relation to this god?
Can you define god? (Not what people say he is, but god himself. What you experience).
Another bonus question. Why the abrahamic god? Why not debate the Hindu god, the Shinto deities, the Buddhist devas?
