The 1964 exhibit has never been characterized by Orly as a birth ceertificate. The 1964 exhibit is said to be a certification that a 1961 BC exists, in Kenya, with the doctor named as the delivering doctor, etc. Fabricating rabbit holes is a ticklish task isn’t it? Even WND has made the mistake of mischaracterizing the Orly exhibit.
Wouldn’t you still have the actual BC just ~3 years after the birth? Or I should say I wonder why you wouldn’t?
