Where was it defined to begin with?
“An individual born to a U.S. citizen parent - whether in California or Canada or the Canal Zone - is a U.S. citizen from birth and is fully eligible to serve as President if the people so choose.”
Its pretty clear that the facts and relevant legal opinion is does not support your statement, Thackney. I linked the first analysis I found but there are many others in greater or lesser depth. This is not a non issue however the media tries to make it one. It is frequently dismissed because it seems over complicated but it is extremely important and relevant to the current election and to recent elections.
