Excellent point. It raises so many interesting points. Are numbers an invention by man, in which case this is just a strange accident. If not an invention of man, what are they? Did they always exist? How did they come to exist? Are numbers evolving? Do they exist independent of sentient beings? Do numbers prove that God exists? The "why" question then becomes very intersting.
I have to rest now, my head hurts.
LOL, exactly. It obviously wasn't created to be a mystery, it just is a mystery. Take 2 advil and post again tomorrow.
