Q1: Do we need a God?
A1: It depends. If it is a good God, probably yes. But goodness is not an essential part of God by my definition. Besides, what does good mean anyway.
Q2: If we do need a good God, does it makes God to be true?
A2: Of course not. What you desires, no matter how strong it is, has nothing to do with the truth value.
Q3: So does God truly exist?
A3: I really don’t know. But I just occasionally bothered by this ultimate question. I live my life on the assumption that He doesn’t exist or He has no interests to interfere my life. Until now, I lived quite content with such ideas bearing in mind.
