To me it makes no sense that Creator+Creation is greater than the Creator. This would pan out as saying essentially that creation, by itself...is great. which is not my belief. Creation without a creator simply has no value.
John 1:3(NIV)
3 Through him all things were made; without him nothing was made that has been made.
An added flaw in your theory is that you state that Y could be expanded infinitely. Perhaps matter could be expanded infinitely in theory, but life? No way. For a believer, Life is "In Him". A believer rejoices at being made alive in Christ. Life only exists because of a Creator of all seen and unseen.
An unbeliever, in contrast, declares that I Am regardless. I live, and thus I have value.
A believer pays homage to the Creator of life, while an unbeliever tends to deify self by virtue of being alive.
