It's kind of an awkward question, like asking why gravity exists. We don't really know why; it's just the way it is.

But it's based on the concept of causality, which determines which events can affect others. In traditional physics, an event could affect those taking place after them without violating causality. In relativistic physics, an event can only affect those taking place after them and within a certain distance determined by the amount of time between them. The distance and time are related by the speed of light.

So you can't go faster than the speed of light because that would violate causality.
