It would be very odd for large mammals to be the only things in universe exhibiting self awareness. Usually when something exists in nature, it's everywhere - gravity, radiation, nuclear forces. Self awareness is probably just another one of these things. Rock is self aware of being a rock, sun is self aware of being a star, human is self aware of being a human, humanity as a whole is self aware of being humanity. Now, obviously experiences of being a star are totally different from experiences of being a human and one can not will them/itself into being the other. Things are happening to each according to laws of physics and self awareness is just along for the ride.
