By the same argument, there is no proof that the immense amount of information within the simplest DNA could code itself. Most scientists today believe that the universe had a beginning. And that it had to happen all at once. After all, of you had matter and energy, where would you put it? So, if space, matter, and energy come into existence, the 'cause' can't be within the universe that just came into being. Matter can't create itself. It is reasonable, notice I didn't say proof, to say that the 'cause' existing outside our universe can be explained as an all knowing, all powerful being, exactly like God. The universe is very finely tuned. Change gravity, either more or less than it is right now, nothing exists.
