Technically all objects have an event horizon, the special feature of black holes is just that they are actually smaller than their event horizon
Every object has a Schwarzschild radius, but only if ~~objects are~~ an object is smaller than ~~their~~ its own Schwarzschild radius (black holes) it defines an event horizon, i.e. by all means of physics, we cannot "see" what is going on inside.
