"There is a tangible, beautiful, amazingly intricate world - and you ask me how I prove there is a Creator of it? C'mon, you have to do better than that to cop out of acknowledging that just as a song had a composer, this beautiful world has a Creator. "

Now Grose, you will have to do better than that yourself! All that you have said simply boils down to "because I said so". You assign an answer to a question that cannot yet be answered simply because you need some sort of closure.    "It is a beautiful world - must be gods doing."   Philosophically that answer works, but that does not make it true.    As Bill D pointed out, you started with a conclusion and you are trying to justify your conclusion.
