I believe in them. I have read quite a bit about them, and the best minds that are experts in Quantum Physics seem to think that they exist. But, because they are so small (if an atom was the size of the visible universe, a string would be the size of a tree), we likely won't be able to know much about them beyond theory.
String theory is only hypothetical. In fact, I'm not sure if it is even testable
