The quality of being omnipotent (all powerful) is an impossible property, either in reality or even in the imagination. Quite simply, can an omnipotent being make an object so big that even he can't lift it? Any answer leads to a being that is less than omnipotent. We know this as kids, but are quickly taught to not ask such questions.
Omniscient (all knowing) doesn't fair any better really. An omniscient being would know everything that has happened, is happening, and will happen. Which makes all human activity preordained, even me typing these words would be scripted and known by such a being from time immemorial.
The "effect, or a manifestation" of such a being and "control some part of nature" would indicate some observable and measurable effect. Yet there is nothing that points to such, unless you want to argue for the anthropic principle, which is like a puddle of water proclaiming how perfectly the hole in the ground fits his shape.
And this is where my atheism comes from. It's with these two characteristics of the supposed Abrahamic ("God") that has lead me to the conclusion that such a deity is illogical. And since other deities don't seem to measure up to these two characteristics I conclude they're illogical as well...along with the plethora of supernatural entities defined by humans. It is at that point I cease caring. I can't say that I'm "fence sitting" because...my position is..I don't believe the supernatural exist nor do I care. It makes for an interesting philosophical discussion/debate though.
