By the fact that nothing in nature happens all by itself. If nothing in nature can happen all by itself, then nature can't cause itself and must be caused by the only remaining possibility that which is uncaused. God is the uncaused creator and intelligent designer-Churchwork

This argument is nothing more than special pleading at it's simplest and most obvious. First, churchwork, you make the argument that nothing happens in nature all by itself. However, of course, this argument then applys to your god...if nothing happens in nature all by itself then god needs a creator. However, you quickly exempt your god from this very logic. Let's take a look at the special pleading fallacy:
Special pleading is a form of spurious argumentation where a position in a dispute introduces favorable details or excludes unfavorable details by alleging a need to apply additional considerations without proper criticism of these considerations themselves. Essentially, this involves someone attempting to cite something as an exemption to a generally accepted rule, principle, etc. without justifying the exemption.
We see then that your attempt to exempt god from your own argument is, in fact, nothing more than special pleading. The attempt to cite something as an exemption to a generally accepted rule, principle, etc, without justifying the exemption.
Whereas, nature itself needs no such exemption. At the heart of all that is is energy. You, trees, rocks, water, are all ultimately energy. We know that energy can neither be created or destroyed. This is the first law of thermodynamics:The First Law states that energy cannot be created or destroyed; rather, the amount of energy lost in a steady state process cannot be greater than the amount of energy gained. The First Law clarifies the nature of energy. It is a stored quantity which is independent of any particular process path, i.e., it is independent of the system history. If a system undergoes a thermodynamic cycle, whether it becomes warmer, cooler, larger, or smaller, then it will have the same amount of energy each time it returns to a particular state. This is both mathmatically and experimentally proveable. So, there is no need for me to resort to any sort of special plea for the consideration of why energy has to be considered eternal because of (fill in the blank). Whereas god DOES need to have special considerations applied which are themselves untestable, unverifiable and unprovable. Again, the very definition of special pleading.
