I think the OP was asking 'why was I BORN this brain and not that brain?' - Not 'why not many brains at the same time or (atleast) many brains during the course one lifetime' (which does ofcourse appear to be impossible albeit fun to imagine
).
This is a real philosphical issue, maybe the philosophical issue as far as scientifically-valid metaphysics is concerned. It's a tricky one - I couldn't understand it until I was an adult. Just getting your head round it -as well as returning to it in reflection- is a mystical experience in itself.
Underscore, you could summarise your (and science's) answer as 'pure chance'. The only well-known answer from religion is ofcourse past-life karma, while
mentallyskilled wrote:
if you were someone else youd still be who you are
implies an underlying identity (i.e. soul/"God's plan") which many religions supply, thereby getting round this problem.
Comments about 'optical illusions _ _ tricking you to believe something that isn't real'{/'errors'} and 'being (far from) the truth' are irrelevant if we've already acknowledged the connection between brain and consciousness, but on the other hand, I'm not sure if I can confidently say that asking the OP question won't lead to a lifetime of mental illness _
