Yes, there are reasons why you consider yourself the same as some particular person and not another. That doesn't prevent other people from having other reasons for considering themselves identified with other bodies, as for example people who believe in reincarnation. Their belief may be less natural than yours, but it is neither more nor less objective (i.e. neither belief has anything objective about it, at least as far as we can tell.)

Some people justify claims of reincarnation by claiming to remember past lives, not merely to "identify with" them. The belief does have something objective about it: it can be tested. Such claims have generally failed of substantiation.
In short, my reasons are objectively good; theirs are objectively bad. What do you mean by "less natural", if not this?
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
