Your strange phrase: “’A natural born citizen’ is someone who was an American citizen at the time of their birth”, is meaningless. How, in your mind, is it possible to be a citizen before birth?

Nobody said anything about "before birth."
A baby is born. What country is it a citizen of? No country? The country of one or both parents?
If your mother was an American citizen, you were born an American citizen. Your mom didn't have to fill out any paperwork or anything. You were a citizen at the time of birth.
Seriously, this isn't difficult stuff here.
