Congratulations Dawkins for making post # 1000.
Finally, arguments concerning causation must not be made lightly. In physics causality involves preceding events, however this breaks down at the particle level due to Heisenberg 's uncertainty principle, and also under quantum field theory, where there is time reversal symmetry -- the laws of nature are the same if time moves backwards. The "arrow of time" that we perceive is due to enormous statistical improbability of, for example, a broken cup on the floor putting itself together and rising back to the table from which it fell.
The new understandings of physics in the last century have considerably outdated those early arguments.
You are responding to PLC's post that "no one has yet proven that there is or is not a god". What you are referencing is an "argument", not a proof. That argument dates back to Plato and Aristotle. According to the site you cite, the "contingency" aspect of lines 1 and 2 leads to a false conclusion in line 4.http://en.wikipedia.org/wiki/Cosmological_argument
The cosmological argument could be stated as follows:
1. Every finite and contingent being has a cause.
2. Nothing finite and contingent can cause itself.
3. A causal chain cannot be of infinite length.
4. Therefore, a First Cause (or something that is not an effect) must exist.
