Actually, it's only an assumption of me that other people than me have consciousnesses (it the soul sense). Yes, consciousness feels like magic, I can't explain why. But why should I assume other people have it too? Just because they are "similar"?
Why not because they can talk about it? As you point out, your own consciousness (insofar as that's a thing that exists at all) is self-evident to you, but when you talk about it, are you actually referring to it?
If so, then it would, at least, be pretty implausible that other people would appear to talk about their own consciousness if it weren't something that they themselves also actually have.
If not, then there's some even weirder coincidence afoot: you experience consciousness, but when you talk about your own consciousness, you're actually talking about something different than the consciousness you actually experience.
Basically, either consciousness manifests itself physically to the extent that people are at least able to refer to it in speech and writing, or it doesn't, meaning we can't actually refer to it at all despite the fact that we appear to be discussing it. In the former case, the fact that people outside of your own perception of consciousness claim to refer to consciousness would suggest that they too actually can refer to it, and thus experience it in some way.
In the latter case, either it's pure coincidence that we merely appear to be discussing a phenomenon that actually exists (but cannot actually be discussed), or consciousness doesn't exist at all.
