Does God Exist?

This is the skeleton of my version of Plato's cosmological argument. I'll put some meat on it later, when I figure out how. Also, I still need to determine all the implications. The definitions in the glossary are mostly my own, except where I've indicated.I welcome criticism, as long as it is kind.

1. If the universe came into existence from non-existence, then its cause must be outside of itself.

1.1 Like all abilities, the ability to bring an object into existence from non-existence requires power.

1.2 An object which is not already in existence has no power at all.

2. The universe came into existence from non-existence.

2.1 An object cannot have more than one age at any given point in time.

2.2 If the universe did not come into existence, but has existed from eternity past, then it has an infinite number of ages simultaneously.

2.2.1 At any given time (t1), the universe would be infinity years old.

2.2.2 At any given time afterward (t2), the universe would be both infinity and infinity + (t2-t1) years old.

2.2.3 Ad infinitum

3. Therefore, the universe must have a cause outside of itself.
