I'm not going to comment so much on this, but there was one thing that caught my eye, and that was this:
14. The universe is 4 billion years old - singular
I would call that general and metaphysical. You would probably get away with singular, but there is room for debate here.
One could argue that the universe itself is a metaphysical phenomenon, and the statement that the universe is "4 billion years old" is not in itself a scientific fact. It is a metaphysical interpretation of many scientific facts.
I don't know, but maybe bringing this up can earn you some extra points. It does raise the issue of the distinction between scientific and metaphysical, as the two are by no means clearly separated from each other.
And if we are to believe the most recent work in unified field theory, there is an even closer link between the metaphysical and the scientific that ever assumed before.
