[After a brief discussion about Occam's Razor and its role in defining the possibility of external agency in the origin of the Universe...]

[Your theory includes two major elements: The Universe and some sort of supernatural First Cause. How is that less elements than the theory that includes just the Universe?]

Which is more plausible an event? Jesus was born with just Mary, or Jesus was born through Mary and Joseph.

With your logic, occam's razor follows that Jesus must have be born just based on Mary, because adding Joseph is adding elements. And there is no evidence to support the claim in either direction.

Total nonsense.
