‘official expression of dependence upon, and gratitude to any Supreme being is forbidden, thereby effectively conveying that atheism is the official faith of the government.‘
Atheism isn’t a faith.
Belief in a supreme being is, and takes on many different forms and interpretations.

Which they cannot "prove" nor have I "proved" my position, but both sides offer evidence they believe supports their hypothesis which for both side is stated a warranted fact.
Which again, means that to believe that an exceedingly vast, systematically ordered universe, exquisitely finely tuned for complex life with its profound intricate complexity and extensive diversity, can be all a result of purely natural processes requires much faith. More so i submit, than that the universe logically testifies to design, requiring a First Cause (at the least), that of a being of supreme power and intelligence being behind the existence of energy and organization of matter, and laws regarding the same.
And try not to rely on your previous recourse of "Where is it claimed that the universe if finely tuned for life" and as if the Universe is not related to life on earth.
