When reading the Ontological Argument, I had stopped at the end of the Anslem section and read it aloud to a friend. At that point, I brought up Klingons. Certainly we know what a Kingon is and what they look like and how they behave - but do they exist? As in the movie "The Ten Commandments" - God is depicted and explained, etc., but does that make him real? If we read "Star Trek the Next Generation" and become familiar with Wharf, does that mean there are Klingons? So, if we read the Bible does that mean there is God? Anyway-I agree with Gaunillon here.

The Causal Argument is a little more convincing. But the criticism of "why just one" or "why personal" shoots a big hole in it for me.

For the Contingency Argument it is the composition fallacy that stands out to me. And also the Law of the Conservation of Mass and Energy. From what we have already learned, there were animals that once existed that are now extinct, but the universe has continued to exist. Humans-yes we may become extinct sometime, but the universe will probably continue. Maybe we'll just end up nuking ourselves into some future evolved beings science and history lessons.
