The Human Truth Foundation. The Universe Could Not Have Been Created by God. The Failure of First Cause Arguments.

In answer to the question why does the Universe exist, the traditional theistic answer is to simply state that God did it1,2. The belief that "everything must have a cause, therefore God exists" is called a First Cause argument. But that merely results in new questions: (1) why did god create the Universe? and (2) why does God exist? If it is valid to say "everything has a cause except God", it is more likely that everything has a cause except the Universe. Both have one exception. If God doesn't need a cause because it is infinite, it is more likely that the natural Universe has existed forever and therefore doesn't need a cause. You therefore make fewer assumptions, and cause fewer puzzles, if you admit that you believe in one uncaused entity, and that that one uncaused entity is the Universe itself.

Aside from causal arguments, there are problems with the nature of god. If God can make plans and think logically, then, logic is an arch-power that encompasses God and gives reason for god's existence. I.e., God, without logic, could not do any creating nor planning. This appears to refute the idea that God could be the creator of logic. If logic was a precursor to God, then, God is not the sole Creator, but merely a side-effect of some logical process. If, in order to avoid this problem, you state that there is no logical reason why God exists, then it is more likely that there no logical reason why the Universe exists, and that instead of assuming that the organisational force is a 'god', it's simpler and more rational to assume that it is the universe itself. It appears that whether God exists for logical reasons or not a fundamental contradiction occurs. The only answer is that creator-gods cannot possibly exist. Atheism is more logical. This is also true if God is placed "beyond logic". Doing this puts God into the territory of irrational fantasy. To retreat into the corner where logic itself is denied, god-believers have admitted that there is no logical basis for their belief. And if it is said that Human logic is incapable of realizing such metaphysical truths, then this also undermines any argument that can be made by one human to another, for the existence of god.
