The math works in theory. As of yet, there is no way to test for the presence of strings; they're too small. Let's run with it though and assume string theory is correct. In the most simplified description, strings vibrate at varying frequencies which in turn give rise to a corresponding fundamental particle. What started the strings vibrating to begin with? What keeps them vibrating? Where did the strings come from? I know you can't answer any of that, and I'm not sure if anyone can, but if it does come to fruition as a TOE, we're going to need answers to those types of questions.
