The golden nugget. Was waiting for that one. For what it is worth here is something to consider.
This material realm is subject to time. Under the influence of this time we are born, grow, dwindle and die. Time is an energy of God. Its something he employs in the material world. He is not subject to time. Thus he is not subject to birth and death. He is eternal. No one created him. Creation only goes on in the material world.
Then clearly god could not have created the universe or there was no need to.
Because either (1) no material world existed before the universe so there could have been no creation which "only goes on in the material world" or (2) there already existed a material world which allowed for the creation of our universe in which case you're back to the infinite regression.
Furthermore you've assumed that the laws that govern our world within the universe are the same laws that our universe as a whole (if that's even an appropriate description) is subject to. Any way you look at it, god is an unnecessary assumption. The truth value of the "god claim" therefore cannot be established by means of this kind of an argument.
