This is a religious argument. If you want to go down that path, then sure; but I suspect that's not what you actually believe.

If we accept subjective feeling as definitive proof that something exists, that opens a Pandora’s box of entities. People have deeply held subjective beliefs about things like God, afterlife experiences, out-of-body experiences, and many others. It seems unfair to me to dismiss this kind of subjective evidence in these cases, while accepting it without question for experience of consciousness.

No conscious person can know if another person is conscious. There is no 'sensation' of experiencing another conscious. Given how many people can and have been fooled by AI, this lack of ability to sense another consciousness is clear.
