Logical reasoning can be based on axioms (like in mathematics), observations (like in science), and ideas (like in philosophy). There are more possibilities and often those are mixed, but this is a start.
To me, it looks like your logical reasoning is based on your ideas, i.e. your personal philosophy. It is not based (or not for the most part) on observations or axioms. You started about 'the universe idea', which stresses this point.
Of course, it could be that it is not your personal philosophy, perhaps you are just playing the devil's advocate or so, but that seems to me largely irrelevant. In that case, you are defending a personal philosophy, just not your personal philosophy.
There is nothing wrong with either of those, but I don't see why you deny it.
