If an object knows that it exists, then this implies that it actually exists. Moreover, assuming that the state of a brain is a mathematical fact about the mathematical theory, then that the object knows it exists is in principle a mathematical implication of the mathematical theory (if observation 2 is correct). Hence it would be an implication of the theory that that theory describes an existing reality.
