I believe there’s some laws / rules which we, as human are not capable of surpass it. We could say our high level of thought is limitless. Einstein said, the only limitation is our imagination. It’s true, in some circumstances, but how do we ensure that our imagination is limitless. Even we can’t imagine, what imagination looks like in the end of endless spectrum of human imagination. That’s the sufficient prove that our ability to imagine is limited. That’s why religion comes into existence. To explain something which beyond our imagination but still in the context we could understand. This knowledge is applicable throughout entire space and time, consistently.
