A version of the cosmological argument could be stated as follows:
1. Every finite and contingent being has a cause.
2. A causal loop cannot exist.
3. A causal chain cannot be of infinite length.
4. Therefore, a First Cause (or something that is not an effect) must exist.
According to the argument, the existence of the Universe requires an explanation, and the creation of the Universe by a First Cause, generally assumed to be God, is that explanation.
My question is regarding #3.Why not??
IMHO with this version of the cosmonlogical argument, regarding statement #2, causal loops pop into and out of existance frequently through time, much as eddies and swirls would in a fast moving river. The existance of any species of living creature might be considered a causal loop. Any repeating causal chain might be considered a causal loop.
Regarding statement #3; I believe, in the space-time continuum, time itself becomes the causal chain.
