Arguments for God's Existence from Contingency

[LostLocke]

Actually i don't see why their must be a first cause . This assumes to much about causes.

Or, let's go further.
What if it turned out to be something like.... A causes B, B causes C, C causes D, D causes A?
That could be waved away as silly nonsense and fantasy, but the reality is that, while there's no indication at all that this occurs inside our universe, there is nothing in our current understanding and knowledge of physics or time that say this can not occur. And that's only inside our universe. If there is an outside to it, who knows how time, physics, or cause and effect work out there.
