Everyone needs a laugh every now and then.
A birth certificate (a.k.a Certificate of Live Birth for children born in certain states) issued by a U.S. state
or territorial government is evidence of citizenship, and is usually accepted as proof of citizenship.”
1st govt laws don't use a.k.a. and 2nd “usually accepted” means doubt and the framers did not put one word in the US Constitution that could be construed with any sort of doubt. Thus the grandfather clause. Even the founding fathers who became president never considered themselves natural born citizens even though they had been born on American soil. When more than one nationality exists at birth, it is the result of man made law, not natural law the reason the word “usually accepted” is used instead of “always accepted”.
