God's existence--A different approach

Too many scientific english words, so forgive me if this is completely off the subject.

I just want to say that the omnipotent God of Abrahamic Religions really raises more questions than what it's trying to answer. I agree with Kalovale that everything that exists has a cause. Also, I believe that there must be some factors that are eternal and have always existed. But I think that the eternal factors cannot be something like an absurdly complex being with magical abilities. In fact, I could be talking about some laws here, like time for example. These little factors have then, over time, lead to series of events, and the big bang.

Basically, it goes like this:

Scientific View/Big Bang: Simple Factors-> Big Bang -> Complex universe

Religious View: Complex Creator->*some cheesy magic tricks here*-> Complex universe

Religious View 2: Complex Creator-> Big Bang -> Complex universe

Basically, people who believe in such an omnipotent God, could just as well believe that this whole universe in all its complexity has always been there. Because, de facto, God of the abrahamic religions is a bigger complex than the universe itself.

Then again, even if we'll manage to confirm big bang theory, it could still be part of a bigger image (paraller universe theory etc. etc.) and honestly, personally it doesn't seem all that infeasible.

Why drop the simple factors from the religious views? What they're potentially saying is

Relatively Simple Factors -> Complex Creator -> cheesy special effects -> Complex universe
|
Relatively Simple Factors -> Complex Creator -> Simple Factors -> Big Bang -> Complex universe

The reason I say relatively simple factors exist before the complex creator goes like this: Either (1) the complex creator always existed, leading to your sequences, or (2) it came from something. If (2), then either it came from something more complex (which should really be called all powerful, since it contains the already existing all-powerful) or something less complex, which I made a note of.

Or, with a slightly different viewpoint as to causality,
>Simple Factors -> Big Bang -> Complex universe>\
\_____________<_Complex Creator_<_________/

Something all-powerful (or 'more powerful than any other entity' if you want that route) doesn't necessarily have to begin existing before the universe - it could just go back and ensure its own creation.
