It states this, it doesn't prove it. It assumes it.
You believe the universe is infinitely old? Uncaused? Both?
There are no proofs of God.
Agree, as explained in #349, supra, since our science lacks the ability to reach outside our own universe and touch Him. We have only the senses/tools/means afforded within the laws of this universe to utilize.
That said, there is plenty of circumstantial evidence--enough to convict God in a court of law--that indicates the presence of an intelligent Creator.
As I've said, if you believe the circumstantial evidence that O.J. Simpson committed murder--and that's all we've got, is circumstantial evidence--people have been convicted based only on circumstantial evidence--then you should also be able to see the myriad forms of circumstantial evidence that we've been living inside an ant farm, and that there's an Ant Farmer out there.
Physics, chemistry, astonomy, biology...all are too "fine-tuned" to be more coincidence.
One astronomer even said (may have been Hoyle) that it appeared that a super-intellect had "monkeyed" with the universe to ensure the creation/survival of life.

I don't know (neither do you). I don't dwell on unanswerable questions. It's a waste of time. But don't let me stop you. Oh, and this also applies to the rest of your post.
