These are all "non-verifiable" statements in the context that are using for veacity.
So too is the statement "There are no gods, there is no God." It is even less possible to demonstrate.
I'll skip Godel's theorem today, except to note that Truth is all about perception, an acceptance of that perception by the consciousness. Restated: there are truths that in any formal system that cannot be verified inside of that formal system.
>G-d exists. Two lines parallel at one point never intersect at another. The sum of the interior angles of a triangle are 180.

The first is merest speculation, as scientifically valid as "Odin exists," "The Great Green Arkleseizure exists," "Frodo Lives!" or "Allah exists." None of these, including "God exists," are valid points for a scientific discussion. At what point in a muder investigation is it fvalid to bring up "God did it?" At what point in your average missing person investigation is it scientifically valid to conclude that being borne bodily up into Heaven is just as likely as a kidnapping?
The second two are true within certain limitations, false in others. I've seen triangles with total interior angles of 270 degrees. I've seen parallel lines intersect at two points. And, in fact, so have you. One does not need advanced hyperspace math of LSD to see such things... they are commonplace, everyday sights.
