We don't even know whether other human beings are conscious, man.
The only thing which we might say with much certainty is that things which are more "like us" along some metric are more likely to be actually conscious, and things which are less "like us" are less likely to be so. Maybe everything is conscious. Maybe nothing except one's own self. But you'll never truly know one way or another, even if humanity invented some kind of Freaky Friday body swap thing.
