It's an interesting topic. What are we? Are we our physical bodies? Are we the information that we've associated? Are we souls/spirits within a shell?
I think so too, but I also think that at this point there is overwhelming evidence that we are our physical bodies - our whole organism - and zero evidence for any rival proposition.
Personally, I don't feel like my physical body (fond of it though I am) is "me." If I woke up tomorrow in a different form, I would still be the core person that I am.
That's really just a guess, best. It appears highly likely that the "core person that you are" is your form. To put it another way, the statement "if I woke up a different person, I would still be the same person" is merely contradictory.
But I'm weird like that, in that my identity exists independent of it. I don't think that's the case for most people.
Again - this is hard to read as anything other than assertion, in this case motivated by feelings of apparent superiority over other people. (I don't mean to insult you at all, but to me the way that statement is written sounds like bluster).
