If God had come from somewhere or dwells anywhere, He wouldn't be God. I am not talking about the anthropomorphic god of religions but the real God, Creator of the universe, Who is always creating. Now, since you committed the fallacy to appeal to authority in the quotation of Han Solo, I thank you for giving me the same right to appeal to the Scriptures. "The universe declares the handiwork of God." That's in Psalm 19:1.
Yes, I agree with you that "I don't know" could be an honest answer, but when you are ready to acknowledge other possibilities, at least until you know for sure what you don't know yet. But to deny the possibility of a Creator for the universe, is pride and arrogance, when you don't know anything about its origin.
I think you have misunderstood what i was saying. From your post declaring what all atheists think it appears you have some unfounded prejudices against that school of Thought. Atheism is not necessarily a belief that god doesn't exist it is a lack of belief that god does, you are confusing anti-theism with atheism. Here is a comparison using geometry; atheism is to anti-theism as a rectangle is to a square.
I never denied the possibility for a universe creator to exist, I denied the certainty.
The quote from han solo was meant to be light hearted and in good humor, just because something is from a work of fiction doesn't mean it is an invalid point, rather I think it is a good point that stands on it's own, Assuming you watched the movies you would know that Han Solo eventually saw things that made him believe in the force. I was actually trying to put out an olive branch.
The point you brought up about the universe declaring the handiwork of god does not stand on it's own it requires faith in the divinity of the book. There are many things in holy books that are good points, not because they are in the books but simply because they are good points.
