I think the truth is stranger than fiction relative to this question.
Asked differently one might muse: "If existed prior to being "born" here on earth (eg. energy is never created or destroyed), then might I be Human+(somethings)?"
Or even "If all time is "simultaneous", than am I at once a human AND multiple other specie?" "Which state would then be my "alien" state?"
Ok, that could go on and on. It gets curiouser and curiouser!!!! LOL
