You just made the assertion. Now please provide some evidence.
Don't believe me? If you are in fact sentient, prove it. Take any lab experiment in which brain function is linked to consciousness and prove that the person whose brain it is is actually experiencing, rather than just saying they are.
It's great to take the philosophical position that other minds than mine exist, but this is not a scientific conclusion-- it's an exercise in pragmatic philosophy. And when you are required to make a philosophical assumption to do science, you don't get to use science to validate that assumption-- circles are circles, no matter who's running in them.
