One big problem with the first premise is right off the bat. It assume that everything has a cause. There are strong indications in QM that not everything has a cause.
So, if that is the case, then the premise is incorrect.
The second problem is that the 'Creator' is uncaused violates the first premises's that everything has a cause. That makes it a 'special pleading', and therefore as a piece of pure logic invalidates itself.
