In legal terms PERSON are of two kinds, natural and artificial. A natural person is a human being. Artificial persons include collection or succession of natural persons forming a corporation; a collection or succession of property tp which the law attributes the capactity of having rights and duties.
If you ever find your self in court or if you have an interest in legal terms pay attention to what is being said because there is equivocal meaning going in the court. From some studying that have been doing, America is a corporation and therefore citizens of America are considered Arficial Persons, thats why we have birth cerfificates and Social Security numbers (which are fairly new documentations). I am not sure how law is ran in other countries but in America there is something fishy going on.
