Consciousness and perspective are temporally stable fixed points in the universe. You come to understand yourself as "you" or "I" because it's the only thing in the world around you that does not immediately change under many transformations.

For example, you can spin around, or change position, or close your eyes, and you're still you. As you navigate and interact with the evolving universe, the only continual, relatively unchanging part of the experience is what your brain uses to differentiate itself from the rest of your perceptions.
