"We know matter exists, and we know consciousness exists, but we really don't know the first thing about how consciousness works."
I hate to say this, but you don't exist. You're just a figment of my imagination, so you can't prove to me that you exist. All of you supposedly "other" people "out there" are images on a VR simulation permanently attached to me that gives me the sensations of sight and sound, and sometimes other more intimate sensations, like the taste of chocolate and bananas or the feel of sweat and heat.
