There's being intelligent, having the ability to think, plan, etc. But that doesn't explain how I feel that I'm here, how I'm conscious. But it could certainly explain why I say I am, being a consequence of how my brain functions. I know I am, because I can feel being conscious, but there's no reason for an AGI to believe that, other than it thinking it's conscious as well (so the same reason I'd believe that you are conscious).
