Superman may be Serbian

This might be an unusual title, but it is logically correct. Here is the deal, researchers have found a mineral with the same composition of Kryptonite in Serbia. So if you follow my logic, the place in which Kryptonite can be found, should also be the place where Superman's rocket from Krypton has landed. Having landed in Serbia, it makes sense that Superman might have been raised in Serbia, Clarko Kentovic, how about that?
