riddle

I am not my body, my body can change but I am still me, who am I?

I am not my emotions, my emotions change but I see them change, who am I?

I am not my memories, my memories fade and new ones are made but I'm still there, watching, who am I?

I am not my identity, who I thought I was has changed but I've been watching myself and that has not changed, who am I?

if I'm not my body or mind, who am I?

am I the sum of all my parts? or is there a soul? is there anything there at all?

if i lost all 5 senses, and lost all of my mind what would be left?
