I defined experience in such a way that only the existence of the model is required. And it's not hard to prove that they have a model of reality - simply ask them to predict what will happen. They don't even have to be right - any prediction about X means you have a model of
X. It might be "everything is random" but it's still a model.
You're free to define experience differently but usually it devolves into defining unknown by unknown.
