Of course God is unfalsifiable

God's existence cannot be proven false.  Since God is unfalsifiable by definition, being unfalsifiable is a property of God's existence.  Since the statement God is unfalsifiable and cannot be disproven is accepted and supported by scientists and Atheists alike, then Occam's Razor shows the simplest explanation to be valid, since a defined and logical statement with scientific and academic consensus is more likely to be true than an argument against it. 

Calculus cannot be proven to be false.  Calculus doesn't wait for some physical evidence to appear and disprove it since Calculus is already logically defined.  We can't prove Calculus exists as a physical thing, but we know Calculus is valid.  Calculus uses self supporting axioms based on the unfalsifiable laws of logic, where abstract theorems do not require physical testability to be valid.  There are many invalid proofs by amateurs who try to disprove Calculus based on a limited understanding of Calculus and a desire to prove Calculus wrong, yet it doesn't matter if you choose not to believe in Calculus or if you declare all of it invalid simply because you don't like it, as such arguments will not make mathematicians everywhere drop the study of Calculus because you don't think it has sound logic.  No matter how you argue, Calculus cannot be falsified. 

Replacing Calculus with God's existence shows the same properties and the same reasons why arguments against them do not work.  Something can be both logically valid and non-falsifiable.

I got into an argument with a friend of mine lasting an hour without reaching a consent. I told him a story: "a russian goes into a hotel and leaves 100$ on the counter saying that he goes upstairs to see the rooms, and if he doesn't like the rooms he will come back and take his money back. The hotel owner comes after 1 minute, sees the money ant takes it, paying the meat distributor that supplied the hotel restaurant. The meat guy pays the animal food guy that pays for his whore. All with the same 100 bill. The whore then goes to the hotel and pays for her room with the 100 bill and leaves. The russian comes back down takes the money and leaves. And thus, nothing was lost, nothing was gained, but everybody paid their debts." My friend says no this is not true, that a debt was lost somewere, that the circle is not closed etc. Who is right??? with arguments please
