This is a quibble, I know, but technically, evolution is not a theory, when used as an explanation for the origins of life on this planet. A theory is a hypothesis that has been proven by experiment (or formal argument). Evolution is acutally a hyposthesis, and those who know the folly of it should call it that.
Unfortunately, the truth that "nothing comes from nothing" applies to all things, and therefore to God also, unless you do not believe God exists.
There cannot be an argument for the existense of God, just as there cannot be an argument for your consciousness. You know you are conscious, and I believe you are, but neither you or I can demonstrate (that is, actually show it to someone) or prove it.
