First order logic, set theory and God

[T0 Th3 M4X]

Below is a copy-paste of my own thread that was posted in another forum. I'm reposting it here in hopes to spark an intelligent discourse on what I believe to be the most refined proof of God's existence.

Here it goes.

With that being said, I would be more than curious to see if anyone could spot a noticeable error in Hatcher's logical deduction

sigh... the whole thing can be boiled down to 

P1: everything that exists has a cause
P2: The universe exist
P3: the universe has a cause (in accordance with P1 and P2)

C1: the cause is god
P4: God exists
C2: therefore god has a cause (in accordance with above premises)
C3: the cause of the universe doesn't need a cause (no good reason is given to why that is the case) (fallacy of special pleading )

now if the god/original cause doesn't need anything to cause it into existence then why does the universe need a cause? this all amounts to a mundane statement of the obvious that not everything needs a cause.

This ignores the main point of the whole thing.  Whatever you started with has to be self-sufficient to "cause" itself.  So if you determine that it doesn't need a cause, then the explanation would be supernatural, because we know cause and effect applies in the natural world.  So you would need the whole gun, the gun would need to have made itself, then you could fire the trigger. If not, you have to apply something to the natural world that isn't evident.
