That's a pretty serious failure of logical aptitude, especially on a site like this. The point isn't that "god exists" but that "Russia is Christian" because of aesthetics, a somewhat important material fact.
No the point is that faith is meritorious because of aesthetics.
That Russia is christian because of aesthetics, and aesthetics are an argument for the merit of faith implies that the christian faith is more meritorious than, paganism, judaism and islam because it's the prettiest.
"Russia is Christian b/c of aesthetics" is one piece of evidence for the greater argument which is something like "these instances of inspiration demonstrate that faith in the existence of God is reasonable."
