For those who still hold out hope for a concrete answer, or finite conclusion regarding the existence of a superior intelligence, this article definitely lends support.

The author has duplicated the evidentiary approach to the issue, much in the same way as an attorney collects supporting evidence to bolster an argument. But, at all times, an argument is an argument, it is never absolute truth. Thus, any adept skilled scientist could also formulate a well-written rebuttal and present literary quotations, footnotes and accomplish the very same task, which is provoke the reader to think.
That is a lofty goal. However, as in all arguments, opposing sides tend to proceed with a legalized approach, each hoping to convince the observers with evidence, reasoning, argumentation and adversarial critiques. I believe it is important to maintain an open mind, to be observant, to be patient for new discoveries and new information, and to avoid posturing in any position that cannot be absolutely proven with the resources available today.
I can prove the sun rises by asking you to watch the sunrise in the morning. Since it actually occurs, there is physical evidence in motion to confirm the rising of the sun. In the matter addressed by the essay, neither side of the issue has absolute, undisputable, physical evidence to support their cause.
Of course, religionists cannot help but approach issues using dogma or legalized format because that is what the core essence of religion is all about, a set of rules and beliefs about human existence. It's too bad that method is still around and has not been scrapped.
