From my agnostic perspective, "infinite" means "unknown".  Therefore, these statements when interpreted as such become logical to me:
Logic says that there is something unknown that caused the finite.  ... We could form a chain going back and back and back to the unknown.

However, this does not follow:
... if people are willing to believe in an unknown universe, why not believe in an unknown creator?

If we are going to assume, then why not assume that a creator must be created too?


I'm not sure about all that.  Not sure why you just can't deal with infinity for what it means.  But anyway, what I was trying to say is that people who cannot believe in an infinite (or uncaused) creator because of logic somehow choose to believe in a universe that is infinite (or uncaused).  That seems contradictory to me.


The 'who created the creator' question really does not refute anything.  Or at least, it does not refute the position that there is a creator of the universe.
