Let me break down his points in more readable form.

CoinCube believes that because there are truths and infinities in Mathematics that cannot be proven there must be an external infinite entity that exists but cannot be proven to exist.

He also claims that such truth (about existence of such infinite entity aka God) predicates all our system of logic and is required for that system to work truthfully.

He also claims that this infinite entity interacts with the physical world, is the source of the moral code that we should follow.  

He claims that any other moral code that is not dictated by this external supernatural infinite entity is doomed to fail and leads to atrocities and disintegration of societies.
