Who among you believe in String Theory?

[Confuzzled4]

I'm curious as to who out there believes in it and why. I terminated my physics education with a masters degree, so I really did not probe at all into the world of GUTs, but there's such a large number of physicists who treat String Theory as a proven fact I find it interesting. I find the idea aesthetically pleasing and plausible, but I could not begin to wrap my head around the machinations.
